Tokens and Smart-Contracts
Umbrella addresses of tokens and smart-contracts deployed on the blockchain.
Supported Chains
At the moment Umbrella is available on BSC, ETH, Polygon, Avalanche, Arbitrum and Solana.
UMB Token
Umbrella Network's native token is currently deployed on the
- Ethereum Mainnet
- BSC Mainnet
- Avalanche C-chain
These are ERC-20 compatible. The UMB token contract address is below:
0x6fc13eace26590b80cccab1ba5d51890577d83b2
0x846F52020749715F02AEf25b5d1d65e48945649D
0xff38197cceF56149976C6D7F6103eB700C086247
Umbrella Reward tokens (rUMB#)
Umbrella Network's reward tokens - rUMB# are also ERC-20 compatible.
There is a different reward token for each staking period.
Reward tokens are only available on the blockchains where Staking Portal operates. Currently Ethereum and BNB smart chain.
Reward token contract addresses are:
0x1b17dbb40fbed8735e7fe8c9eb02c20984fadfd6
0x0Bdc4eDd85bEe69552D9ad6426E322199915cf79
0xAe9aCa5d20F5b139931935378C4489308394ca2C
Contract Registry
Via the registry you can find current addresses of other smart contracts eg:
- On-chain data
UmbrellaFeeds
- Layer-2 data

Chain
Chain Address 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 Chain address via Registry. Examples will be 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 following value: 'Chain'.
- For BSC testnet: https://testnet.bscscan.com/address/[contract-registry-address]#readContract
- For Ethereum testnet (Goerli): https://goerli.etherscan.io/address/0x77922965C12bD55d6BA71b0c87E68D9F04a919Ba#readContract
- For Polygon testnet (Mumbai): https://mumbai.polygonscan.com/address/[contract-registry-address]#readContract
- For Arbitrum testnet: https://testnet.arbiscan.io/address/[contract-registry-address]#readContract
By using the Read Contract tab and the getAddressByString method, you can read the latest address.
For Solana:
- Devnet: https://explorer.solana.com/address/4SPgs3L7Ey9VyRuZwx4X3y86LSAZXP2Hhpz9Sps4v3iT?cluster=devnet
- Mainnet: https://explorer.solana.com/address/4SPgs3L7Ey9VyRuZwx4X3y86LSAZXP2Hhpz9Sps4v3iT
Audit Reports
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.
