Millions of crypto wallets accumulate small-value assets from rug pulls, meme tokens, and mass airdrops, leaving liquidity unused. Individually, these assets are too expensive to convert due to gas fees and transaction complexity. This results in lost capital that users either ignore or struggle to consolidate.
CRUMBs acts as a smart private pooling mechanism that absorbs low-value assets into a collective liquidity pool. Once assets meet conversion thresholds, they are automatically swapped into stable tokens (ETH, ATOM, SOL, USDT, USDC).
Crumbs solves micro-asset liquidity fragmentation and will use Namada’s MASP infrastructure for Shielding & Swapping.
What do you hope to build in Namada and/or the broader protected ecosystem?
What applications or tools do you personally use that do not exist yet?
What new and compelling products can Namada’s MASP and shielding actions enable?
I hope to build altruistic applications in Namada and/or the broader protected ecosystem, including the project parties and users who create the applications. Therefore, I propose that while providing users of each chain ecosystem with the shielding function, the application can have a slightly more appropriate fee income, which will encourage the creators of each application to be more willing to create privacy applications while protecting the assets of users. For example: the income of a privacy cross-chain bridge is slightly higher than the fee income of a general cross-chain bridge project, and privacy DeFi and privacy NFT also increase appropriate fee income, which is acceptable to users.
Shielded addresses can realize batch sending and receiving functions, making it convenient for system projects to use registered shielded addresses to send and receive tokens.
I hope to create a red envelope chain, which has been submitted to DC mod to realize a new viral marketing model for the ecosystem.
It is hoped that the ecosystem will achieve diversified payment methods, such as investment and consumption models (already submitted to dc mod). At the same time, the financial management end can achieve unlimited cooperation with new chain TVL, achieve unlimited expansion of users, and unlimited multi-chain.
The ecological donation system built by Namada can be connected with culture. It is not just a donation, but also a belief, a religious culture, and is conducive to the destruction of nam. It has been submitted to (dc mod).
Privacy is the other side of transparent blockchain. All open and transparent blockchains can re-realize privacy, including the following:
Privacy cross-chain bridge
Privacy DeFi
Privacy assets
Privacy NFT
Privacy multi-signature wallet
Privacy AI automatic quantitative trading
Privacy market making
Privacy custody privacy
Payment
Privacy***
Privacy identity (zero-knowledge proof)
Institutional-level privacy transactions
Privacy chat
Privacy data storage: Encrypt content through distributed storage such as IPFS, and only authorized users can decrypt
Exchange privacy wallet to prevent hacker attacks
Anonymous (privacy) voting system
Idea Description:
Creation of a decentralized domain name system similar to ENS but fully integrated with Namada’s MASP, ensuring the privacy of domain name owners and their addresses. Shielded ENS allows users to send assets to domain names without publicly revealing the recipient’s address or balance.
Example scenario: A user sends tokens to a simple and intuitive domain like “sekto.nam”, but only the domain owner can view incoming transactions and control the shielded address associated with the domain.
Main Tasks and Deliverables:
Develop a basic smart contract or Namada module managing domain registration and linking to shielded addresses.
Implement a straightforward mechanism for sending and receiving shielded tokens through domain names without revealing actual addresses.
Create an intuitive web interface for registering, searching, and verifying domain names.
Importance and Benefits:
Significantly simplifies the process of sending shielded assets: users use convenient and familiar domain names instead of complex, long addresses.
Helps expand Namada’s audience by attracting users already accustomed to the convenience of ENS who seek similar tools with enhanced privacy.
Fully aligns with Namada’s core mission protecting user privacy with user-friendly and intuitive UX.
Potential Users:
Broader crypto audience familiar with ENS, but seeking solutions offering high levels of privacy.
There are standalone apps popping up everyday like Polaris, Infinex, Legend, Rebind, stable, Defi.app, Zeal wallet etc and would be nice to integrate with them somehow. Users could get a choice to shield their activities. Next narrative and user acquisition will probably happen with these apps. The idea of vault is also gaining traction. Integrating/partnering with veda.tech (https://x.com/veda_labs) for outside echosystem yield while preserving privacy to Namada for not sophisticated users.

BBS-style game → private player state (eg. location, hidden player stats, inventory) is hidden but can be proven within the game and revealed during certain kinds of encounters
Shielded service integration - eg. shielded payment for Nym or Sentinel VPN service
private proxy ICS-27 control - proxy contract - send a shielded IBC tx from Namada with a memo to perform an action, sending your ICS-27 message to voting, staking, etc.
ChatGPT:
1. User submits a shielded transaction on Namada
- Funds are in MASP
- The tx includes an IBC transfer to Osmosis
- The IBC memo includes a wasm call:
{
"wasm": {
"contract": "osmo1...your_cosmwasm_contract",
"msg": {
"trigger_axelar": {
"eth_contract": "0xYourContract",
"method": "doSomething",
"args": ["0xAlice", "0x42"]
}
}
}
}
2. IBC + PFM forwards packet to Osmosis
- ibc-hooks delivers memo to the designated CosmWasm contract.
3. CosmWasm contract calls Axelar gateway
- Osmosis contract invokes Axelar’s general message passing contract:
axelar_gateway.call_contract(
target_chain = "ethereum",
target_contract = "0xYourContract",
payload = encode_args("doSomething", ["0xAlice", "0x42"])
)
- Axelar handles routing the call, optionally including token transfers.
4. Axelar relays message to Ethereum
- Message lands on Ethereum, calling your target contract.
- Your contract logic executes on Ethereum.
Donations or crowdfunding UI
Payroll app → paying contributors, employees, or partners without publicly revealing amounts or recipients; while enabling the payee to maintain verifiable records and recipients to have the same
Quest style game → clues reveal nested viewing keys that ultimately lead to a treasure
Neutron outpost PoC - private voting (can see vote choice and tally, but not source) using ibc hooks (cosmwasm)
Shielded access control PoC
Declutter wallet consolidator app - makes it easy for user to consolidate multiple wallets
Privacy that fades - like selective unshielding after time N, or until a condition is met.. not sure if this is currently possible though
Thanks all for the lovely submissions here! I will review and compile these into an initial set of RFPs by Friday. I may reach out to ask questions. Excited!
I’ve posted the first draft microgrant bounty here - feedback welcome, planning on activating it in the next few days if the structure seems clear.
A few questions on some of the proposals here:
@amadison79 I really like the Telegram bot idea, would you be up to write this as a series of successive milestones (of progressively greater complexity), similar to my draft above? I’d be happy to sponsor it, but I think you have a better idea of what users want here (I don’t really use Telegram bots myself).
@EmberStake What do you imagine as the form of the shielded donations app – would it be a website? A mobile app? Something else altogether? I like the “shielded donations” idea in general, but I’m wondering about how exactly users would interact with this system.
Shielded payment for Nym or Sentinel VPN service - what exactly should the user flow look like here? What apps (e.g. existing VPN apps) would this need to integrate with?
Ethereum wallet seeding PoC app - what user flow are you envisioning here? Would this be a webapp? What wallets would it interact with? etc.
PoC Agoric asset management proxy (remote-controlled private defi) - would you also be open to doing this with CosmWASM on Namada (which we’ve been working on anyways for Wormhole)? What kind of user flow and DeFi management functions do you imagine, exactly?
Right now, I think the app should be a website with a mobile-first design. The goal is to make it as simple to use as platforms like Patreon or Buy Me a Coffee.
On the donatee side, people will make a profile on the site and get a donation link. They can share this link on social media, or use badges (for example on GitHub), or add widgets to their personal websites.
On the donor side, they shouldn’t need to know anything about Namada or even hold USDC. The app will support donations from many chains and tokens, using swap and bridge services in the background. The idea is to make it easy for anyone to donate using what they already have.
We could also add some extra perks for people who donate using NAM , like no fees. In the future, we can also add support for fiat payments.
I think if the UX is done right, this has the potential to become the go-to donation platform between the Web3 community and open source developers or activists, especially those already using Zcash or Monero to accept donations. Both sides would enjoy the convenience of paying with any asset, while still keeping their donation activity more private.
There are still some technical challenges to reduce the trust assumptions in parts of the system, but I believe these can be solved over time with a few iterations
should be fairly simple–create new wallet with MetaMask, connect to local webapp, import new wallet address, send ETH from Namada (bridging is handled). not sure if user may want to have a record saved locally. perhaps this could be added to Namadillo as a feature
Remote-controlled private defi
doesn’t matter which bridge or platform. the user should be able to use eg. USDC in Namada shielded pool to a) deposit into Aave b) receive Aave’s deposit tokens, like aEthUSDC, back into shielded pool c) redeem aEthUSDC for USDC to be back in Namada shielded pool
Sentinel
not sure how the user flow should go–i’m shifting focus to consider mobile-ready solutions (i’m very accustomed to desktop/laptop, but.. )
i looked at what appears to be Sentinel’s Android app (tho there are a few mobile apps), which uses $P2P tokens (rebrand from $DVPN) exclusively
the app asks for 1.33k $P2P for 30d of VPN, and uses google pay to let you buy $P2P with a credit card. but it’s $27 USD for 5k $P2P vs buying 5k $P2P for ~$1.25 on a DEX
there’s a “Swap to Get DVPN” button that goes to the swapfast.app site (by Leap Wallet). if you have crypto, you can then swap into $P2P, transfer to the wallet provided by the app, and access the service
