#1 for VietnamCoinbase CDP Server Wallets (API-key wallets)#1 globallyProvider states broad availability A backend API that creates EOAs whose private keys are generated inside Coinbase's AWS Nitro Enclave TEE, then signs and broadcasts transactions from them on seven EVM mainnets and Solana, with import and export of the raw private key both exposed as REST endpoints.

What the relayer is authorised to do, and whether you can keep the address — 9/10What a stolen API credential can do before anyone notices — 9/10#3 for VietnamOpenZeppelin Relayer#3 globallyProvider states broad availability An AGPL-licensed Rust service a backend team runs itself to submit transactions from its own EOA on EVM, Solana and Stellar networks, where the signing key stays in the buyer's own keystore file, HashiCorp Vault, AWS KMS, Google Cloud KMS, Turnkey or Coinbase CDP account rather than in a vendor's vault.
What the relayer is authorised to do, and whether you can keep the address — 10/10Where the gas float sits and how you get it back — 9/10#4 for VietnamSequence Transactions API (Relayer)#4 globallyProvider states broad availability A hosted relayer that accepts a signed Sequence smart-contract-wallet transaction bundle from a backend, fronts the network gas either from a Builder-funded sponsorship balance or from an ERC-20 fee transaction included inside the bundle, and submits it on chain-specific relayer hosts (52 published in the vendor's OpenAPI servers block, of which 21 mainnet hosts answered live on 11 August 2026).
What the relayer is authorised to do, and whether you can keep the address — 9/10Where the gas float sits and how you get it back — 7/10#5 for VietnamCircle Gas Station#5 globallyProvider states broad availability Circle fronts network fees for transactions sent from Circle-hosted Programmable Wallets — through a Circle-owned, upgradeable ERC-4337 paymaster proxy on EntryPoint v0.6 on its supported EVM mainnets and fee-payer accounts on Solana and Aptos — governed by console-configured gas-spend policies and billed back to the developer's card after the fact.
Where the gas float sits and how you get it back — 8/10Exactly-once execution and stuck-queue recovery — 7/10#6 for VietnamOpenfort backend wallets#6 globallyProvider states broad availability A custodial server-side signer: Openfort generates and holds an EVM or Solana private key inside a GCP Confidential Space TEE, exposes sign/import/export over a REST API gated by a fail-closed rule-based policy engine, and can also submit transactions for that wallet via EIP-7702 delegation — a send the policy engine sees only as signEvmHash, so its transaction rules do not run — with gas optionally sponsored from a prepaid project credit balance.
What the relayer is authorised to do, and whether you can keep the address — 9/10Where the gas float sits and how you get it back — 7/10#7 for VietnamGelato Relay#7 globallyProvider states broad availability A hosted meta-transaction relay, as last documented on 2026-08-11: the buyer's backend posts a target address and calldata to Gelato's JSON-RPC API with an API key, and Gelato's executors front the gas and submit the transaction, billing a prefunded USDC "Gas Tank" balance held on Polygon.
