Why DID-agnostic Verifiers Are the True Gatekeepers of Adoption

DID-agnostic verifiers are the gatekeepers. The critical control point for user onboarding is the entity that verifies credentials, not the wallet that holds them. Applications must integrate with verifiers like SpruceID or Veramo to access users, making these infrastructure providers the true adoption bottleneck.

Wallet-centric strategies are obsolete. Teams building custom identity wallets fight on the wrong battlefield. The winning strategy is to ensure your protocol's credentials are verifiable by the dominant, wallet-agnostic verification standards like W3C Verifiable Credentials, not by a specific app.

Evidence: The Ethereum Attestation Service (EAS) demonstrates this shift. Its schema registry is meaningless without widely integrated attesters and verifiers. Adoption scales when verifiers like Coinbase's Verifier or Gitcoin Passport attestations are accepted universally, independent of user wallet choice.

Protocol-specific verifiers create walled gardens. Each identity standard like Verifiable Credentials (VCs) or Soulbound Tokens (SBTs) builds its own verification logic, forcing applications to integrate multiple, incompatible trust layers. This fragmentation kills developer velocity and user experience.

Agnostic verifiers abstract the underlying DID. A verifier like Ethereum Attestation Service (EAS) or a zk-proof verifier checks the proof's validity, not its origin format. This separates the trust mechanism from the identity data, enabling universal composability across chains and standards.

The verifier is the new liquidity layer. Just as UniswapX abstracts liquidity sources, an agnostic verifier abstracts trust sources. Applications plug into a single verification endpoint, accessing credentials from Ceramic, ENS, or Gitcoin Passport without custom integrations.

Evidence: EAS schema adoption. Over 2.5 million attestations have been created on Ethereum and Optimism using EAS schemas, demonstrating demand for a standardized, chain-agnostic verification primitive that applications like Optimism's AttestationStation and Coinbase's Base build upon directly.

Integrated verifiers offer performance guarantees that DID-agnostic systems cannot match. A project like zkSync or Scroll can optimize its entire stack—prover, sequencer, and verifier—for a single use case, delivering lower latency and higher throughput. This creates a powerful go-to-market advantage.

The economic model is deceptively simple. Projects avoid the operational overhead of managing multiple verifier integrations. The cost of a bundled solution from a single vendor like Polygon or Optimism is predictable, while the cost of a fragmented, multi-verifier future is unknown.

Market pressure forces short-termism. In a race for TVL and users, builders prioritize shipping features over architectural purity. Choosing a turnkey solution from StarkWare or Arbitrum is a rational, time-to-market decision, even if it creates technical debt.

Evidence: The L2 landscape is dominated by integrated stacks. Arbitrum, Optimism, and Polygon zkEVM each control their own proving and verification. The market has rewarded this approach with over $40B in combined TVL, validating the vendor lock-in trade-off.
