Cross-Chain Credential Interoperability Solutions

Deploy a secure, non-custodial bridge for Decentralized Identifiers (DIDs) and Verifiable Credentials (VCs) using W3C standards. Enables users to port their identity and credentials between Ethereum, Solana, and Polygon without re-verification.

Real-time, event-driven synchronization of credential status and attestations. Our relayers ensure revocations and updates are propagated across connected chains in < 2 seconds, maintaining a single source of truth.

Custom smart contracts for issuing and verifying VCs with multi-chain fee abstraction. Reduce user transaction costs by up to 70% through batch processing and optimized proof verification (Groth16, Plonk).

Pre-built, certified adapters for major protocols: IBC, LayerZero, Axelar, and Wormhole. Accelerate integration and future-proof your stack against ecosystem changes. Deployment typically completes in 2-3 weeks.

Built-in compliance modules for travel rule (FATF), sanctions screening, and jurisdiction-aware credential filtering. Maintain regulatory adherence across all connected chains with configurable policy engines.

Integrate a single SDK to verify user credentials (SBTs, VC proofs) across Ethereum, Polygon, Arbitrum, and other EVM chains. Eliminate the need for separate verification logic per network, reducing integration complexity by 70%.

Leverage our audited, non-custodial relayers and zero-knowledge proof circuits to port verifiable credentials between chains with cryptographic integrity. Built with OpenZeppelin standards and reviewed by third-party auditors.

Optimize credential state updates and verification calls using layer-2 scaling solutions and gas-efficient smart contract patterns. Achieve sub-second finality for permission checks, cutting user wait times and operational expenses.

Deploy with built-in compliance hooks for regulatory frameworks (e.g., GDPR right-to-delete, travel rule). Maintain immutable, chain-agnostic audit trails of all credential issuances and verifications for reporting.

We begin with a comprehensive security-first design review. Our team analyzes your existing credential schemas and proposes an interoperable architecture, followed by a formal audit of all smart contracts and integration logic against the latest OWASP and ChainSecurity standards.

Our engineers build the core cross-chain messaging layer and credential verification modules. We implement using battle-tested frameworks like Axelar GMP or LayerZero, ensuring gas-optimized, non-custodial credential attestations and revocations across chains.

We deploy the complete solution to a dedicated testnet/staging environment. This phase includes full integration testing with your dApp frontend, load testing under simulated mainnet conditions, and final security validation before mainnet deployment.

We manage the coordinated mainnet deployment across all supported chains (EVM, Solana, Cosmos). Post-launch, we provide 24/7 monitoring with Chainscore's proprietary dashboards, alerting for bridge security, and guaranteed SLA-backed support.
