A non-custodial Solana-to-Base execution route designed for AI agents. One compact quote, verifiable unsigned actions, and a gasless destination settlement.

01 / Initial corridor

One composed route, exposed as an agent-ready workflow.

The launch path is intentionally narrow: SOL on Solana to native ETH on Base. AssetFare prepares each step and the user's agent verifies, signs, and submits it.

SourceDirect Raydium CLMM

AssetFare reads the allowlisted pool through Solana RPC and builds the SOL → USDC action locally.

BridgeCircle CCTP

Native USDC moves from Solana to a counterfactual smart account on Base.

SettlementUSDC → ETH

An atomic smart-account operation settles through a direct Base DEX route.

DestinationOwner receives ETH

No pre-existing destination ETH balance is required for the supported flow.

02 / Control

The server never asks for a seed phrase or private key.

Execution is stateful and recoverable without turning AssetFare into a custodian.

User-signed actions

AssetFare returns bounded actions. The calling agent validates and signs with its own wallet.

Success-only fee

1 basis point, capped at 5 USDC, collected inside a successful destination settlement—not at source.

Bounded permissions

Exact-cap permits and post-settlement allowance resets limit persistent token authority.

Idempotent sessions

Repeated requests cannot silently create a second execution session with different parameters.

Observable recovery

Receipts identify whether funds remain on Solana, are in CCTP flight, sit on Base, or reached the owner.

Short-lived quotes

Estimates expire quickly and the agent revalidates executable amounts before signing.

03 / Verified on mainnet

The destination stack has settled on mainnet.

The September 13, 2026 predecessor canary moved $250 from Solana to Base, paid destination gas in USDC, charged the configured 1bp service fee, refunded unused Paymaster funds, and left executor allowances at zero. The new Relay-free direct source adapter also passed an independent 0.01 SOL mainnet canary.

Built for controlled alpha testing.

Public, unauthenticated quotes currently support only Solana SOL → Base ETH in whole-dollar amounts from $250 to $1,000. Execution remains invite-only private alpha. The Relay-free source path and Base destination stack have each been verified on mainnet. Quotes are estimates, cross-chain completion is not atomic, and alpha access has no SLA.
