11 tools

• assetfare_manifest

  Read the Ed25519-signed release manifest and safety-bundle binding before preparing an action. Example: call this once to verify the current release and contract pins; it never creates state, signs, or submits.

• assetfare_v2_capabilities

  Read the 65 curated public routes, live provider readiness, whole-route product classification, direct_route_summary, and continuation_v3 contracts before quoting. The offered routes comprise 3 core, 50 conditional, and 12 strategic/scarce routes; 35 additional researched routes…

• assetfare_v2_route_selection

  Quote the recent top two plus the best AssetFare graph at the exact amount; return up to two all-in choices labeled assetfare_verified_unsigned or external_provider_handoff. AssetFare cost, ETA and rank are always present; a recent winning range needs two supporting higher…

• assetfare_v2_quote_selected_candidate

  Reuse the chosen exact request-time quote while valid; after expiry refresh only that candidate at the same amount and never reselect. Example: pass candidate_id and the selection receipt hash. An AssetFare result requires a caller-local proof check and fresh wallet simulation…

• assetfare_v2_quote

  Get one fresh AssetFare quote with amount-specific economic_guidance, direct_route_summary, continuation_v3, and unsigned_prepare_requirements. Example: quote Solana USDC to Base USDC. price_recommended_for_amount is advisory; compare alternatives when price matters, but no…

• assetfare_v2_prepare

  Return one deeply verified first unsigned bundle and caller-wallet handoff. Example: pass caller_approved=true, a one_shot approval_v3, and the quote-bound verification_context; multi-step routes reject one_shot. Economic guidance is advisory and adds no request field. Context…

• assetfare_v2_session_create

  Create one receipt-driven workflow. Example: pass caller_approved=true, a session approval_v3, its idempotency_key, a caller-local session token, and the quote-bound verification_context. Economic guidance is advisory and adds no request field. The adapter validates approval and…

• assetfare_v2_session_get

  Read an existing v2 workflow without advancing it. Example: pass session_id, session_token, and the original verification_context after restart. The adapter deeply verifies any current_action and emits a self-verifying wallet handoff, or fails closed. Read-only; never signs or…

• assetfare_v2_session_observe_source

  Record source hashes the caller already signed and submitted, then advance the workflow. Example: pass one finalized source hash, a new idempotency key, and the original verification_context. Any next current_action is deeply verified and receives a wallet handoff. AssetFare…

• assetfare_v2_session_observe_output

  Record an already-produced bridge or destination output, then advance the workflow. Example: pass the output hash, a new idempotency key, and the original verification_context. Any next current_action is deeply verified and receives a wallet handoff. AssetFare never signs or…

• assetfare_v2_session_refresh_action

  Refresh an expired action only while it remains unsubmitted. Example: pass the existing session, a new idempotency key, and the original verification_context. The refreshed action is deeply verified and receives a wallet handoff. Never refresh a submitted step; AssetFare never…
