Smart Contract Addresses

Gamma protocol is currently live on Ethereum Mainnet, Ropsten testnet and Kovan testnet.

Mainnet

Core Modules

External Contract, Pricers, Callees

Kovan

Note that 0x is deprecated on Kovan, so our kovan testnet won't allow creating, buying, or selling orders. We recommend testing with Ropsten if you need 0x functionality.

If you don't need 0x functionality, Kovan is a better choice, since Chainlink (our oracle source) is on Kovan and will automatically report prices.

Ropsten

If you need to trade oTokens using 0x, we recommend using Ropsten, since that is the only testnet 0x supports.

Note that Chainlink (our oracle source) doesn't support Ropsten, so if you need a historical price for a specific oToken, please reach out to us on Discord.

Also note that the Ropsten release currently doesn't have partial collateralization as it is not yet updated to the v2.0.0 release. It will be updated in the coming weeks.
