DAO treasury contracts

Treasuries and token vesting, audited before deployment.

Treasuries and vesting are where a contract bug costs real money and cannot be undone. We write small, readable contracts on audited building blocks, test them heavily, have them audited independently, and build the app signers and holders actually use.

// what matters here

What is different in this industry.

01

Small contracts on proven parts

We build on Safe and OpenZeppelin where they fit, and keep our own code short enough that an auditor can read every line.

02

Audited before anything is deployed

Contracts go to an independent audit firm before mainnet. The audit is a separate line you can see, and findings are fixed before launch.

03

Keys planned, not improvised

Signers use hardware wallets, thresholds suit the treasury's size and there is a written plan for a lost key or a departing signer.

04

No promises about token prices

We build the machinery of distribution and custody. We do not design tokenomics for price, and nothing we ship claims a gain for anyone who holds a token.

Multisig treasury for a DAO

Hypothetical. Not a client, not a result.

// The problem

A DAO's treasury sits behind one or two keys, payments to contributors are sent by hand, and members cannot see what was paid or why.

// What we would build

A multisig treasury with spending policies written into audited contracts, and a web app where signers review and approve payments and members see the treasury's history in plain terms.

// What is in it

  • A multisig wallet with spending limits and roles set by the DAO
  • Payment requests with purpose, approvals and the transaction that settled them
  • A public view of balances and payments for members
  • Contracts audited by an independent firm before deployment
  • Signer onboarding with hardware wallets, and a key recovery plan

Token vesting and claim portal

Hypothetical. Not a client, not a result.

// The problem

A token issuer tracks team, advisor and investor vesting in a spreadsheet and sends each unlock by hand, which is slow and easy to get wrong.

// What we would build

Vesting contracts that release tokens on the agreed schedule, with a portal where each holder signs in, completes the identity checks your compliance team requires and claims what has vested.

// What is in it

  • Vesting contracts with cliffs, schedules and revocation where agreements allow
  • A claim portal with wallet sign-in and an identity check before the first claim
  • An admin view of every grant, what has vested and what has been claimed
  • Contracts audited by an independent firm before deployment
  • English and French for holders

// Stack

  • Solidity
  • OpenZeppelin
  • Foundry
  • Next.js
  • Identity verification API

// questions

Questions we get about this.

Which chains do treasury and vesting contracts use?

Ethereum and the main EVM networks such as Base, Arbitrum and Polygon, chosen for where your community and assets already are. We can also work on our own block-DAG chain, ATON Chain, where it fits.

Can a vesting schedule be changed once deployed?

Only as the contract allows, which is set when you design it. Revocation for departing team members is common; changing a holder's schedule without their consent usually is not, and we make that choice visible up front.

Who pays for the smart contract audit?

You do, through us or directly, at the audit firm's price. The estimate shows it as a third-party cost, separate from our build.
