Skip

  • Name: Skip
  • URL: https://www.skip.build/
  • Tags: cosmos-ecosystem ethereum-ecosystem
  • Category: cross-chain control-flow infrastructure / interoperability routing-and-relaying middleware / solver-based fast-bridge and oracle stack
  • Summary: Skip is best read as a cross-chain control plane for sovereign and app-chain ecosystems, not as just another bridge aggregator. The useful surface is the whole stack: Skip Go for route construction, Smart Relay for execution handling, Go Fast for solver-financed speed, Eureka for proof-heavy verification, and Connect for validator-run oracle delivery. That is a lot more power than a quote API.
  • What it does:
    • Provides Skip Go API, client libraries, and a widget for building cross-chain swaps, transfers, onboarding flows, and bridge-and-act workflows across multiple ecosystems
    • Composes routes across underlying DEXes and messaging or bridge systems including IBC, CCTP, Hyperlane, Eureka, Stargate, Go Fast, and Axelar
    • Offers Go Fast, a solver-based fast-bridging system where third-party solvers front destination-chain liquidity and settle later on the source chain
    • Offers Smart Relay, a relaying layer that uses full route context to reduce user signing steps, improve reliability, and handle packet delivery across supported bridges
    • Integrates IBC Eureka, which extends IBC-style light-client verification into Ethereum and related EVM environments using SP1 proofs
    • Operates Connect, an oracle system designed to deliver offchain data to onchain apps using a chain’s native validator set, vote extensions, and ABCI++-style consensus hooks
    • Publishes open-source repos for the Go client/widget stack, Go Fast contracts, and a reference solver implementation
  • Key claims:
    • The homepage says Skip is building tools for sovereign communities and frames Skip Go as one endpoint for cross-chain control flow and multi-domain interactions
    • The Skip Go docs say the API composes many underlying swaps and bridging operations into multi-hop routes so users can move from one token and chain to another in a single end-to-end flow
    • Those docs explicitly list IBC, CCTP, Hyperlane, Eureka, Stargate, Go Fast, and Axelar as supported underlying systems, which is strong evidence that Skip is packaging orchestration above multiple bridge and messaging layers rather than operating as one isolated bridge
    • The Go Fast docs describe a permissionless solver model where users submit intents on a source chain, solvers fill on the destination chain within seconds, and settlement happens afterward through cross-chain verification and relaying
    • The Smart Relay docs describe an intent-aware, user-centric, universal relayer that can reduce transaction count, improve route availability, and take over relay execution across supported bridge legs
    • The Eureka technical overview says it uses the full IBC light-client security model, SP1 proofs on Ethereum, and no multisig dependencies for verification, while also noting that the initial rollout still uses a permissioned relay set for liveness and safety
    • The Connect docs say the oracle is run with a chain’s native validator set and can use vote extensions and ABCI++ so offchain data arrives with chain-native security assumptions and millisecond-fresh block updates
    • The public Go Fast contract and solver repositories show Skip open-sourcing both the contracts and a reference solver stack, including order filling, settlement, verification, fund rebalancing, and Hyperlane-based communication components
  • Whitepaper: Public docs reference a Notion-hosted Go Fast whitepaper, but the clearest current source surface is the official site, docs corpus, and open-source repositories. Primary-source notes are saved in ../whitepapers/skip-protocol-primary-sources-2026-05-09.md.

Internal linkages

  • Best peer reads for route-construction control planes: across and relay.
  • Faster-fill branch nested inside the broader stack: skip-go-fast.
  • Keep this note on route composition, solver admission, Smart Relay behavior, and the Connect / Eureka operator surfaces rather than on every bridge path Skip can sit above.

Governance / control risk

  • The leverage is in route composition, solver admission, Smart Relay behavior, rollout phases, and which chains or assets get first-class operational support.

  • Connect adds another operator surface: validator incentives, data-source policy, and how much oracle trust is really being imported into the local chain.

  • So the right read is not Skip supports many bridges. It is that Skip decides how much multichain complexity gets exposed, abstracted, or quietly normalized.
