Deployed contracts

This section of the documentation is dedicated to offering a comprehensive overview of all deployed contracts. We strive to maintain the accuracy and completeness of these addresses, but please be aware that there may be instances where the information becomes outdated.

Curve DAO¶

Curve DAO consists of multiple smart contracts connected by Aragon. Interaction with Aragon occurs through a modified implementation of the Aragon Voting App. Aragon’s standard one-token, one-vote method is replaced with a weighting system based on locking tokens. Curve DAO has a token (CRV) used for governance and value accrual.

Here is a list of contract deployments that are used in the Curve DAO:

Vesting contracts for the Curve DAO token:

Despite being launched on Ethereum, the Curve DAO Token can be bridged to various chains:

Aragon

Aragon Voting App deployments are the main entry points used to create new votes, vote, check the status of a vote, and execute a successful vote.

Aragon Agent deployments correspond to the different owner accounts within the DAO. Contract calls made due to a successful vote will be executed from these addresses. When deploying new contracts, these addresses should be given appropriate access to admin functionality.

The following token addresses are used for determining voter weights within Curve’s Aragon DAOs.

The Emergency DAO is deployed at:

Fee Receiver¶

Fee Burner¶

Burners are a crucial element of the fee payout system in Curve. They convert the collected pool fees into an asset that is later exchanged for USDC. Eventually, the USDC is deposited into the 3Pool, and the fees are distributed to veCRV holders in 3CRV. The type of burner used depends on the tokens present in the pool.

Here is a list of burner contracts currently in use:

Curve Router¶

Routers that performs up to 5 swaps in a single transaction and can do estimations with get_dy and get_dx.

EVM Sidechain Gauges¶

The RootLiquidityGaugeFactory contract on Ethereum is utilized across a majority of sidechains, with the exception of Fraxtal, Binance Smart Chain, Avalanche, and Fantom. Each of these networks hosts its own version of the RootLiquidityGaugeFactory contract. While the functionality across these contracts remains consistent, they differ in their contract addresses.

Address Provider¶

Contract functionality is documented here .

Meta Registry¶

Contract functionality is documented here: MetaRegistry

Each MetaRegistry is integrated into the chain-specific AddressProvider at ID = 7. To get the most recent contract, users are advised to fetch it directly from the AddressProvider contract.

For example, to query the MetaRegistry contract on Ethereum, one can call get_address(7) on the AddressProvider:

>>> AddressProvider.get_address(7)
'0xF98B45FA17DE75FB1aD0e7aFD971b0ca00e379fC'

Rate Provider¶

Contract functionality is documented here: RateProvider

Each RateProvider is integrated into the chain-specific AddressProvider at ID = 18.

For example, to query the RateProvider contract on Ethereum, one can call get_address(18) on the AddressProvider:

>>> AddressProvider.get_address(18)
'0xA834f3d23749233c9B61ba723588570A1cCA0Ed7'
