Universal Gateway Transaction Platform
Ship chain-abstracted transactions without the infrastructure maze.
One integration for gasless transactions, swaps, and private tokens—built for teams that want a reliable path from intent to finality.
https://api.ugtp.io/v1Prepare, sign, submit, and track a gasless transfer through one UGTP flow.
→Start with identityUnderstand the account modelThe account is the owner EOA, activated by an EIP-7702 authorization.
→Handle every networkHandle the operation railsBranch on the prepare response to sign a hash, typed data, or a transaction.
→Exchange assetsBuild a swapQuote a LI.FI route, prepare it gaslessly, then sign and submit it.
→Get started
Get started
Authenticate, pick an environment, and make the first call.
One integration for gasless transactions, cross-chain routing, and private tokens.
→Get startedWhat UGTP isMove tokens on several chains without making your users hold the chain's own coin to pay for it.
→Get startedQuickstartMake the first authenticated call, then build the same prepare–sign–submit loop for every operation.
→Get startedEnvironmentsValidate against staging, then move the same flow to production.
→Get startedAuthenticationSession JWTs administer projects and keys; project API keys authenticate application traffic.
→Concepts
Concepts
The account model, the rails an operation travels, and the networks that differ.
An account is the owner EOA itself, activated per network by an EIP-7702 authorization.
→ConceptsOperation railsThe prepare response decides what the account signs. Branch on it, not on your own network table.
→ConceptsAvalanche C-ChainThe same API through a different mechanism, plus one setup step the other networks do not have.
→Build
Build
The flows: transfers, swaps and cross-chain sends, allowances, and networks.
Prepare, sign, submit, and poll a gasless operation through to a terminal status.
→BuildPrivate tokensAvaCloud's Encrypted ERC-20 (eERC) on Avalanche C-Chain — wrap a supported token into its encrypted form, move it with the amount hidden, and unwrap it back.
→BuildSwapsExchange one token for another as a single gasless operation, on LI.FI's routes, on one chain or ending on another.
→BuildAllowancesOne ERC-20 allowance per token, granted once, before the first gasless operation on the executor rail.
→BuildNetworksWhich chains this deployment serves, and which token an operation can pay its fee in.
→Operate
Operate
Track an operation to finality, reconcile its fee, and handle failure.
From signing through submission, confirmation and finality — and how status reaches you.
→OperateFeesReserve against the worst case, show the expected charge, reconcile what settled.
→OperateDeployed contractsThe addresses an operation touches on supported mainnets.
→OperateErrors and recoveryBranch on the coded reason, and retry only what the response says is safe to repeat.
→Architecture & services
Architecture & services
How the pieces fit, which services are ours and which are third-party, and the standards underneath.
The path from intent to execution, node by node. What each service along it owns is on the services page.
→Architecture & servicesServicesWhich parts are UGTP's own, which are third-party, and what each one owns in an operation.
→Architecture & servicesStandardsEIP-7702, EIP-712, ERC-20, EIP-2612 and ERC-2771 — what each one does here.
