Contract addresses

Check a YieldBasis contract address here before you sign a transaction or integrate a contract. All addresses are on Ethereum mainnet.

To confirm a role, read it from the contract. For example, call markets(i) on the Factory for a market, or POLICY() on a pool for its pool policy.

Core contracts​

This table lists the protocol-wide contracts and the role of each. Where the Contract column names a getter, call it on the parent contract to confirm the address.

Pool policies​

A pool policy is a contract that a Curve Cryptoswap pool calls to set its swap fee, its price_scale target, or both. To check which policy a pool runs, call POLICY() on the pool. For what each policy does, read Pool policies.

Policy of each market pool​

This table maps each active market pool to its pool policy:

The pools of markets 7 to 10 run Twocrypto v3.0.0 (the v3 pools). The pools of markets 0 to 6 run Twocrypto v2.1.0d. That code has no POLICY() function and no policy hooks.

YBOraclizedPolicy contracts​

This table lists the oracle-report policy contracts and the Pyth contracts that they use:

Curve contracts that control pool policies​

This table lists the Curve contracts that control pool policies:

ContractAddress
Curve Twocrypto factory0x98EE851a00abeE0d95D08cF4CA2BdCE32aeaAF7F
Pool admin proxy (factory.admin())0x97aA696e37659Fb4f0B53824246d802Df40E980A

Curve ownership voting0xE478de485ad2fe566d49342Cbd03E49ed7DB3356

The pool admin proxy has two roles:

  • dao(), the Curve Ownership Agent. Only this role can call execute(). A Curve DAO ownership vote uses it to attach or replace a pool policy and to set the pool fee parameters.
  • emergency_dao(), the Curve Emergency DAO 0x4679…1e0c. Both this role and the dao() role can call emergency_parameters(). On the v3 pools of markets 7 to 10, a call to emergency_parameters() sets mid_fee, out_fee, fee_gamma, adjustment_step_min, adjustment_step_max, and ma_time on a pool.

For every role that can change a pool policy, read Pool policies in Roles and permissions.

Net pressure​

These contracts route part of the LT admin fees into a crvUSD incentive campaign on Merkl. For how the campaign works, read Net pressure and the PID controller.

The first row repeats the FeeSplitter from Core contracts, because the getters in the next rows start from it:

The YB DAO owns MerklPIDDriver. Its pressure_lts() list holds the LTs of markets 7 to 10.

Lending oracles​

These price oracles serve lending markets that accept yb-LP as collateral. The ENS name oracles.yieldbasis.eth resolves to YBLendingOracle, and oracles-ll.yieldbasis.eth resolves to the LlamaLend oracle factory.

For how each lending oracle prices a yb-LP share, read Lending oracles.
