Skip primary sources — 2026-05-09

Classification takeaway

Skip is most useful as cross-chain control-flow and orchestration infrastructure rather than as a simple bridge aggregator. Its primary materials combine a routing layer (Skip Go), a solver-filled faster-than-finality bridge path (Go Fast), a route-aware relaying layer (Smart Relay), an IBC-to-EVM verification path (Eureka), and a validator-native oracle product (Connect). The reusable insight is that Skip is trying to become the middleware that decides how users and apps move across chains, which means practical authority can accumulate in route composition, relay behavior, solver economics, gas-prep logic, and the data services that app chains depend on.

Primary sources reviewed

  1. Official site — https://www.skip.build/

    • Best high-level framing for the current product surface.
    • Positions Skip as infrastructure for sovereign communities, with Skip Go for cross-chain control flow and Connect for validator-native data delivery.

  2. Skip Go introduction docs — https://docs.skip.build/go

    • Best concise source for the API’s core role.
    • Says Skip Go composes many underlying swaps and bridge hops into one end-to-end route and supports bridge-and-act workflows.

  3. Skip Go docs index — https://skip-go.mintlify-go.com/go/llms.txt

    • Useful map of the real surface area.
    • Shows how broad the stack is: routing, msgs construction, tracking, Smart Relay, Go Fast, Eureka, client library, and widget flows.

  4. Go Fast docs — https://skip-go.mintlify-go.com/go/advanced-transfer/go-fast.md

    • Best first-party explanation of the fast-bridge mechanism.
    • Describes permissionless solvers fronting capital on the destination chain, then settling later after cross-chain verification.

  5. Smart Relay docs — https://skip-go.mintlify-go.com/go/general/smart-relay.md

    • Best source for Skip’s relayer-control-plane posture.
    • Explicitly frames Smart Relay as intent-aware and user-centric, with the ability to reduce transaction count and improve route reliability.

  6. IBC Eureka technical overview — https://skip-go.mintlify-go.com/go/eureka/eureka-tech-overview.md

    • Best source for where Skip’s interop story differs from plain solver routing.
    • Says Eureka uses full IBC light-client verification, SP1 proofs on Ethereum, and initially permissioned relayers for liveness.

  7. Connect introduction docs — https://docs.skip.build/connect

    • Best source for Skip’s oracle/control-plane expansion.
    • Positions Connect as a data-delivery oracle secured by a chain’s own validator set with vote extensions and ABCI++.

  8. Skip Go repo — https://github.com/skip-mev/skip-go

    • Confirms the public client/widget implementation exists and is not just a docs façade.
    • Useful as evidence that the integration surface is meant for external builders.

  9. Go Fast contracts README — https://raw.githubusercontent.com/skip-mev/go-fast-contracts/main/README.md

    • Good engineering-level source for the intent, solver, fulfillment, and settlement flow.
    • Also clarifies ERC-7683 compatibility language.

  10. Go Fast solver README — https://raw.githubusercontent.com/skip-mev/skip-go-fast-solver/main/README.md

  • Best source for the operational solver stack.
  • Shows the reference solver includes filling, settlement, verification, rebalancing, and Hyperlane-linked communication.
  1. Go Fast whitepaper link — https://skip-protocol.notion.site/EXT-Skip-Go-Fast-b30bc47ecc114871bc856184633b504b
  • Public docs point here as the whitepaper location.
  • It was not meaningfully retrievable in this pass, so the active summary relies on the docs corpus and open-source repos instead.

Why it stays in the active corpus

  • Strong comparison class for interop-routing middleware, fast bridges, solver systems, and app-chain control planes.
  • Useful because it bundles several layers that are often analyzed separately: routing, relaying, fast fills, proof-based interop, and oracle delivery.
  • Worth keeping because it helps ask where cross-chain authority is actually moving: bridge contracts, relayers, solvers, route engines, or middleware vendors that own the end-to-end UX.
