Client
Builds the intent, holds the account key, and signs whatever the prepare response returns.
Architecture
The path from intent to execution, node by node. What each service along it owns is on the services page.
System architecture
A coordinated path from intent to execution
UGTP keeps client signing explicit while coordinating rails, fees, routing, and network execution behind one gateway.
UGTP Gateway
Authenticates public requests, resolves the project's fee terms, decides which rail carries the operation, and orchestrates the account, swap, fee, private-token, and transaction APIs.
UGTP Engine
Builds the operation for its rail, relays or broadcasts it, and tracks it to a terminal status.
UGTP Paymaster
Sponsors gas through EntryPoint v0.9 and collects the fee from the transferred asset on the UserOperation rail.
Avalanche executor
Executes an account-signed EIP-712 request on Avalanche C-Chain and pulls its fee against a one-time allowance.
LI.FI routing
Returns same-chain swap and cross-chain route execution data.
Chainlink price feeds
Prices the fee's dollar-denominated parts in the fee token, read on chain by the fee-collecting contracts.
Blockchain network
Executes the submitted operation or the routed transfer.
