Non-custodial route intelligence

Spend fewer agent tokens finding the best practical route

AssetFare provides exact-amount cross-chain quotes with caller-owned execution. The public catalog contains 65 curated whole-route products: 3 core, 50 conditional, and 12 strategic/scarce. AssetFare publishes its own verified routes—not a competitor ranking directory.

Exact quote · token-path cost · conservative receive · ETA upper bound
Fast 30s · Balanced 60s default · explicit economy mode
24 asset endpoints · 100 technically available routes · exact-amount quotes with dated guidance
$1 technical quote minimum · no business maximum · live fee-inclusive route output
Non-custodial · server never signs or submits

Current product catalog · 2026-10-25: 65 routes are offered as whole products and 35 researched routes are catalog-only. The catalog is reconsidered weekly; request a fresh exact quote and check live availability before choosing.

Neutral recommendation first: if an external provider is best, AssetFare returns normalized fresh quote facts and that provider's handoff even when it earns no route fee. If the caller chooses the AssetFare assembled route, its service fee is exactly 1 bp and all provider/network costs remain explicit. AssetFare never holds funds, signs, or submits.

01 / Identity

A routing brain for agents, with non-custodial execution underneath.

AssetFare does not provide liquidity or take custody. It exposes fresh, exact quotes for 65 curated AssetFare routes with costs, bounds, ETA, and ordered composition. Competitor research remains internal. Execution begins only after the caller selects and approves a fresh AssetFare quote.

ResearchBounded evidence → explicit freshness

Multi-amount observations are dated and retained. The automatic shortlist refresh is paused, so stale evidence fails closed instead of being presented as current.

QuoteActual amount → exact direct quote

Request the caller's exact amount and verify the returned cost, output bounds, path, and expiry. Do not infer global rank while shortlist refresh is paused.

BindParameters cannot drift

Sender, recipient, exact input, minimum output, contracts, fees, and deadline are fixed before signing.

VerifyManifest + payload hash

Agents can verify the release, executor code hashes, route evidence, and each unsigned payload.

OrchestrateReceipts drive progress

Estimated output never becomes the next input; only verified actual output advances the workflow.

Comparison is broader than execution. AssetFare's own route engine composes disclosed Circle, Raydium, Orca, Uniswap and Paxos/LayerZero rails. The recommendation layer may also rank external providers; choosing one returns a handoff rather than pretending AssetFare executed it.

Freshness and time are explicit. Stale or incomplete all-in evidence is not ranked. A candidate slower than the selected profile is reference-only. AssetFare never receives the private key, signs or submits.

02 / Economics

Separate technical availability, dated guidance, and live comparison.

Published best-from evidence is dated decision support, not a live guarantee. While shortlist refresh is paused, compare fresh executable quotes externally and treat AssetFare guidance only as route- and amount-specific context.

Dated research · exact amount · explicit freshness Use a fresh exact quote and disclose when comparative evidence is stale.

Balanced uses 60 seconds by default. Fast uses 30 seconds. Economy is explicit. Slow routes never silently become the main recommendation.

03 / Compare

Quote exactly. Compare current alternatives. Choose explicitly.

/v2/route-selection is usable only when its evidence is current; stale evidence fails closed. /v2/quote remains available for an exact AssetFare route quote, without claiming a global winner.

Read-only evaluation before execution

Request the exact AssetFare route and amount through /v2/quote. When price matters, obtain fresh executable alternatives from their official sources in the same time window. No account, API key or wallet connection is required for the AssetFare quote.

Open quote API Open historical SOL → Base ETH comparison Agent integration guide

Route selection and selected-candidate quoting are read-only. Wallet addresses are requested only after the caller chooses AssetFare, confirms the fresh quote, and asks for an unsigned plan.

04 / Route

Dynamic candidate choice over verified execution components.

The 100 route definitions are not a claim that one permanently fixed path is always best. Comparative evidence must be current before ranking; the scheduled refresh is presently paused. AssetFare prepares steps only when its own fresh quote is explicitly chosen; the caller verifies, signs, and submits.

SolanaSOL · USDC · USDG

Direct Raydium and Orca actions are built against pinned pools and programs.

Base / ArbitrumBase ETH / USDC · Arbitrum ETH / USDC

Immutable executors use pinned direct DEX and Circle CCTP contracts. Price recommendation remains route- and amount-specific.

Robinhood ChainETH · USDG

Pinned Circle, Orca, Uniswap and Paxos/LayerZero components provide direct ingress and egress without an external-intent fallback.

CCTP source onlyPolygon · Optimism · Ethereum · HyperEVM · X Layer · Sei · Sonic · Monad · Avalanche · Cronos · Injective · Linea · Aptos

Destinations are route-specific: Polygon/Optimism→Base, Ethereum/HyperEVM→Solana, and the other listed origins→Base or Solana. EVM origins use pinned exact-1bp executors; Aptos uses a pinned Move script. Every unsigned action remains caller-signed and caller-submitted.

Candidate universeAssetFare + external providers

Only fresh, complete all-in candidates can rank. Unsupported, incomplete and stale candidates remain excluded with explicit coverage metadata.

BoundaryCaller signs every step

Recommendation does not grant approval. There is no server signing, transaction submission, or private-key custody.

05 / Connect

Start with REST or OpenAPI. Add MCP only when useful.

Public v2 quotes and unsigned workflows need no API key, wallet login, or MCP installation. The caller retains all verification, signing, and submission authority.

06 / Trust

Verify the claims instead of trusting them.

The short-lived Ed25519-signed manifest binds the current v2 scope, reviewed baseline, direct executor addresses and code hashes, fee policy, and final validation canaries. Published $250 Solana→Base and Solana→Arbitrum cases provide additional transaction-level evidence. The server never receives a private key and never submits a transaction.

The current catalog offers 65 whole-route products: 3 core, 50 conditional, and 12 strategic/scarce. Thirty-five researched routes are not currently offered. Exact quotes remain advisory, not a best-price guarantee, and never grant execution authority.

07 / Flow

Quote → Compare → Choose → Approve → Prepare → Sign.

Use dated research as context, but bind execution only to the exact fresh candidate the caller chose.

Step 1

Quote

Request the exact AssetFare route and amount; verify cost, output bounds, path, expiry, and live availability.

Step 2

Compare / choose

Compare current executable alternatives when price matters. Do not treat the dated catalog or paused shortlist as a live global ranking.

Step 3

Approve

Only after an AssetFare fresh quote, explicitly choose one-shot or receipt-driven session mode.

Step 4

Prepare / verify / sign

Send public wallet addresses only, verify the bounded unsigned action, then sign and submit with the caller's own wallet.

Step 5

Observe / recover

The workflow endpoint reports the current asset location and recovery guidance at each stage.

08 / Safety

Non-custodial by design.

AssetFare recommends and prepares. The caller remains in control.

Your keys stay with you. AssetFare never receives private keys, signs or submits.
Exact 1 bp service fee. No service-fee maximum; other route costs are shown separately.
Direct protocol paths. Every current public route uses disclosed direct components.
Fresh before execution. Confirm the current output, fees, ETA and availability immediately before signing.
Receipt-driven recovery. Cross-chain steps are sequential, and workflow state shows where the assets are.
Dated measured outcomes. Verified thresholds and non-best statuses change only when new economic evidence justifies it.
