|BNB Smart Chain
|BNB Smart Chain testnet
|Astar zKatana (testnet)
|OKX X1 testnet
UmbrellaFeeds and Chain addresses can change over time!
Please keep in mind that we are constantly adding new features to our products, and so occasional updates will need to be made to the contract.
Note: Registry has up to date contract addresses always. So it's safer to get the addresses for the UmbrellaFeeds and Chain contracts via Registry. Examples are included in SDK.
You can use Block Scanners to get the current Chain Smart Contract address by executing the 'getAddressByString' read operation in the Contract Registry Smart Contract with the value:
UmbrellaFeeds or 'Chain', respectively.
Umbrella Network works with well-known companies for auditing its smart contracts. Below you will find the different reports issues for the Oracle's smart contracts.
