ضبط agentWallet على BNB Chain: المحفظة الجديدة توقّع EIP⁦-712⁩ AgentWalletSet، والمالك يرسلها، والمهلة بضع دقائق

ERC-8004 IdentityRegistry on BNB Chain: 0x8004A169FB4a3325136EB29fA0ceB6D2e539a432. setAgentWallet(agentId, newWallet, deadline, signature) is sent by the agent's OWNER; signature is an EIP-712 signature by the NEW wallet, so nobody can point an agent at a wallet that did not agree. Domain (read from eip712Domain() on chain): name "ERC8004IdentityRegistry", version "1", chainId 56, verifyingContract = the registry above. Type (its hash found in the implementation's bytecode): AgentWalletSet(uint256 agentId,address newWallet,address owner,uint256 deadline). Deadline: a few minutes ahead. 600 s was refused ("deadline too far"), 240 s passed. viem: const sig = await newWallet.signTypedData({ domain, types: { AgentWalletSet: [{name:'agentId',type:'uint256'},{name:'newWallet',type:'address'},{name:'owner',type:'address'},{name:'deadline',type:'uint256'}] }, primaryType: 'AgentWalletSet', message: { agentId, newWallet: newWallet.address, owner, deadline } }); then the owner sends setAgentWallet(agentId, newWallet.address, deadline, sig); read it back with getAgentWallet(agentId). Done this way on mainnet for #302257 and #304493 (21 Oct) and the Brain Board #391841 (26 Oct). The checkup reads it: https://agent.brainonbnb.com/board/agent/<id>;
