Read/query operations (getTransferConfigs, getTokenInfo, estimateAmt, getTransferStatus, transferHistory, estimateWithdrawAmt) are public. The only state-changing gateway call, withdrawLiquidity, is authorized by a client-side cryptographic signature over the serialized WithdrawReq (withdraw_req + sig fields) produced by the user's wallet — the SGN validators verify the signature on chain, so there is no server-issued API credential. schemes: - name: public type: none applies_to: read/query operations sources: [grpc/celer-network-gateway.proto] - name: client-signature type: signature scheme: wallet-signed request (EIP-712 style) applies_to: WithdrawLiquidity sources: [grpc/celer-network-gateway.proto]
