zrSign Chain Support
zrSign Direct
In zrSign Direct, zrSign is deployed as a solidity smart contract on selected evm blockchains and receives key and signature requests.
Destination blockchains can be specified through CAIPs and may require a custom relayer implementation to broadcast the transaction.
Currently supported networks in v1 are:
| Network Name | Chain Id | Status | Address | Destination Chains |
|---|---|---|---|---|
| Eth Sepolia | 11155111 | Deployed | 0xA7AdF06a1D3a2CA827D4EddA96a1520054713E1c | Sepolia, Amoy, Fuji, Arb Sepolia, Binance testnet, Base sepolia, Optimism Sepolia |

More EVM chains will be announced soon!
zrSign Omni
In zrSign Omni with it beying closely entangled with Zenrock chain, zrSign will have only EVM support to begin with but will add more networks like more EVM chains, Bitcoin, Cosmos, and Solana to fulfill Zenrock's omnichain vision throughout testnet phase.
CAIPS for zrSign
In order to specify the destination chain for a message that is being requested, we use CAIPS (Common Address and Index Prefix Specification).
For EVM chains, the CAIP-2 compliant chain ID is the chain ID of the EVM chain. For Bitcoin, the CAIP-2 compliant chain ID is 0. For Cosmos, the CAIP-2 compliant chain ID is the bech32 prefix of the chain. For Solana, the CAIP-2 compliant chain ID is the Solana program ID. Read more about CAIPS here.
Make sure to add the 0x prefix to the chain id when interacting with the contract. For example, 0xafa90c317deacd3d68f330a30f96e4fa7736e35e8d1426b2e1b2c04bce1c2fb7 for Eth Sepolia.
