How to choose a blockchain or Web3 service provider
Enterprise blockchain spend in 2025-2026 has consolidated around three production patterns: regulated tokenisation of real-world assets (RWA), trade and supply chain provenance on Hyperledger or Corda, and selective use of public EVM L2s for treasury and capital markets infrastructure. Speculative pilots have largely been cut. Buyers should pick partners with shipped production references in the specific pattern they are targeting, not partners with a generic blockchain practice.
Three procurement archetypes are emerging. Specialist crypto-native firms (ConsenSys, Chainlink Labs, Fireblocks) lead on public chain and L2 engineering, oracle integration, and institutional custody integration. Big Four and global SIs (Deloitte, EY, Accenture, IBM, TCS, Wipro, Infosys) lead on tokenisation and supply chain programmes where audit defensibility, regulatory mapping, and integration with core banking or ERP dominate cost. Platform vendor services (R3, Kaleido, Luxoft) lead inside their existing customer base where the network is already chosen.

Frequently Asked Questions
What does an enterprise blockchain programme cost?
A regulated RWA tokenisation pilot covering one asset class, on-chain registry, custody integration, and a basic transfer-agent workflow typically runs $1.5-4M in services over 6-12 months. Supply chain provenance pilots on Hyperledger / Corda run $400k-$1.5M. Production deployments scale with counterparty onboarding, integration with core systems, and regulatory engagement; full RWA platforms commonly reach $8-25M over 24 months.
Public chain or permissioned?
For tokenised assets that need broad institutional liquidity, public EVM L2s (Polygon, Base, Arbitrum) and emerging RWA-focused chains are now the default. For supply chain, trade, and identity use cases dominated by a consortium of known counterparties, permissioned Hyperledger Fabric or Corda continue to dominate. Hybrid architectures with permissioned subnets bridged to public liquidity are increasingly common for capital markets.
How do we manage smart contract risk?
Treat smart contract security as a multi-firm independent audit problem. Reputable production deployments use two independent audit firms (typically combining a crypto-native firm such as Trail of Bits, OpenZeppelin, or ChainSecurity with a Big Four assurance engagement), formal verification on critical functions, and an active bug bounty. Avoid sole-source audits and never combine the audit firm with the implementation partner.
Do we need a custody partner?
Yes for any production system that holds, transfers, or settles digital assets on behalf of clients or counterparties. Buy custody as a service from a regulated provider (Fireblocks, Anchorage, BitGo, Komainu) rather than building custody in-house. The regulatory perimeter and operational maturity required for in-house custody now materially exceeds what most enterprise IT functions can deliver.
What contract structure works for blockchain partner work?
Fixed-price for discovery, architecture, and audited smart contract delivery. Time-and-materials for ongoing protocol evolution. Always include source IP assignment, audit report ownership, key ceremony documentation, and disaster recovery for any signing infrastructure. Require evidence of partner-side wallet hygiene and operational security controls before granting access to deployment keys.
