Linkra Gateway — Simple Docs

Linkra Gateway is a cross-chain interoperability layer designed to connect fragmented blockchain ecosystems. It supports verifiable message passing and flexible execution with a modular architecture.

Reliability-first Composable modules Minimal trust ZK-ready

Quickstart

This is a conceptual quickstart. Linkra can be integrated through a single “gateway interface” that abstracts chain specifics via adapters and verification modules.

1) Connect Pick chains and adapters. Normalize events and tx formats.

2) Verify Validate messages with trust-minimized verifiers.

3) Route Apply routing policies and failover strategies.

4) Execute Deliver calls/assets with execution guards + incentives.

Tip: Keep your dApp integration stable. Swap modules (verifier/router/executor) underneath as the network evolves.

/// Conceptual pseudocode

gateway.sendMessage({
  fromChain: "chainA",
  toChain: "chainB",
  payload: { action: "CALL", data: "..." },
  execution: { mode: "atomic", gasLimit: 250000 }
})

gateway.onDelivered((receipt) => {
  console.log("Delivered:", receipt.status)
})

Architecture

Linkra is a layered stack. Each layer can be upgraded without forcing dApps to rewrite integrations.

Adapters Chain connectors that normalize events and state into a consistent interface.

Verifier Trust-minimized proof checks (signatures/light clients/ZK-ready modules).

Router Policy engine for multi-hop routing, app rules, and failover.

Executor Execution environment that applies delivery semantics and replay protection.

/// Example module wiring (conceptual)

gateway.useAdapter("chainA", adapterA)
gateway.useAdapter("chainB", adapterB)

gateway.useVerifier(verifierModule)
gateway.useRouter(routerModule)
gateway.useExecutor(executionModule)

Messages

A cross-chain message moves through normalization, verification, routing, and execution. Receipts can be used to confirm delivery and final execution status.

message = {
  id: "0x…",
  src: { chain: "A", sender: "…" },
  dst: { chain: "B", target: "…" },
  payload: { type: "TRANSFER|CALL", data: "…" },
  proof: { type: "sig|light-client|zk", data: "…" }
}

The gateway aims to keep the user experience simple: request → verifiable delivery → execution receipt.

Relayers

Relayers transport cross-chain messages and can be incentivized by fees. A decentralized relayer set improves liveness and reliability, while verifiers keep trust assumptions minimal.

Relayers should be rewarded for uptime, and slashed/penalized by policy if required by the network design.

Fees

The fee framework is flexible: it can route protocol revenue, compensate relayers, and support application-specific fee logic.

fees = {
  base: "network fee",
  relayerReward: "delivery incentive",
  protocolShare: "optional revenue",
  custom: "app-specific rules"
}

Security

Linkra prioritizes minimal trust assumptions. Verification modules should be designed so relayers cannot forge execution without valid proofs. Future upgrades can include ZK verification for stronger guarantees.

Trust-minimized verification Prefer verifiable proofs over opaque bridging assumptions.

Replay protection Execution should include nonces, receipts, and guarded semantics.

FAQ

Is this a bridge? Linkra is a gateway layer that can support multiple bridge designs through modular adapters and verifiers.

Can I upgrade verification later? Yes. The design is built for future verifier upgrades, including ZK modules.

Does it support custom rules? Yes. Routing and execution can be extended with application-specific constraints.
