Outstaffing seasoned Solidity engineers lets you tackle cross-chain payment protocol challenges now, instead of spending months on recruitment, onboarding and local compliance. You get instant access to developers who have already built token bridges, liquidity routers and inter-ledger messaging layers. We handle payroll, legal and HR, so your core team stays focused on architecture and delivery. Scale up or down on demand, replace any engineer free of charge within 1 week, and keep full IP ownership. It’s the fastest, lowest-risk path to multi-chain revenue.

What Technical Leaders Say
Smartbrain.io embedded two Solidity specialists into our fintech squad in 48 hours. They stabilised our bridge contracts, reducing re-org failures by 37% and freeing my engineers to focus on wallet UX. Vetting quality was obvious from day one—clean code, exhaustive tests, seamless Git etiquette.
Rachel Martinez
VP Engineering
MetricPay LLC
The augmented devs spotted a critical nonce-collision bug in our B2B settlement layer. Fixing it cut transaction disputes by 92%. Onboarding took less than a sprint, proving Smartbrain's outstaffing beats traditional hiring for specialised Solidity needs.
Thomas Lee
CTO
FleetChain Inc.
Needed five extra Solidity engineers for peak roadmap pressure. Smartbrain delivered in a week. Their developers integrated CI/CD, raised coverage to 90%, and improved gas efficiency by 18%. HR paperwork—zero on our side.
Linda Parker
Engineering Manager
HealthToken Solutions
Our logistics chain required atomic swaps across three networks. Smartbrain’s talent built a robust escrow smart contract, passing external audit with no critical findings. Productivity jumped as my core team avoided context switching.
Edward Johnson
Dev Team Lead
CargoLedger Corp.
We went from concept to live Polygon–BNB bridge in 10 weeks thanks to Smartbrain’s senior Solidity contractor. The pay-as-you-go model kept burn low while allowing rapid iteration.
Stephanie Nguyen
Product CTO
GameVerse Studios
Smartbrain paired us with a Solidity dev experienced in on-chain compliance modules. He implemented FATF-ready address screening across chains, letting us pass legal review without onboarding delays.

Industries We Empower
FinTech & Banking
FinTech firms use augmented Solidity teams to launch cross-chain payment protocol gateways that handle real-time FX settlements, CBDC pilots and on-chain compliance. Developers integrate token bridges, liquidity pools and AML screening so banks can transact across Ethereum, BNB and private ledgers while meeting regulatory requirements.
Gaming & NFTs
Play-to-earn studios rely on outstaffed Solidity experts to enable cross-chain NFT transfers, in-game asset swaps and reward payouts. The protocol lets gamers move value between side-chains with near-zero latency, boosting engagement and secondary-market liquidity.
Supply-Chain & Logistics
Enterprises track provenance and automate payments by embedding cross-chain escrow smart contracts. Augmented developers design secure settlement layers that release funds only when IoT-verified milestones are met, cutting disputes and middle-man costs.
Healthcare Data
HIPAA-conscious platforms hire Solidity contractors to build cross-chain payment protocols that tokenise clinical data access and remunerate contributors instantly across networks while maintaining privacy via zero-knowledge proofs.
Real Estate Tokenisation
Property marketplaces leverage outstaffed devs to create multi-chain payment rails for fractional ownership transfers, ensuring investors can trade tokens on preferred networks without liquidity fragmentation.
Energy & Carbon Markets
Clean-tech companies deploy cross-chain payment protocols for renewable-energy certificates and carbon credits, enabling automated clearing between private consortium chains and public markets.
Insurance
InsurTechs augment Solidity talent to craft parametric policies paying out via cross-chain oracles, reducing claim settlement from weeks to seconds and reaching customers on any network.
eCommerce & Retail
Merchants integrate cross-chain payment checkout that auto-routes stablecoin payments to the cheapest chain. Outsourced devs handle smart-contract security, slippage controls and wallet UX.
Telecommunications
Telcos experimenting with tokenised bandwidth credits hire Solidity specialists to build cross-chain micropayment channels, letting customers top-up in one network and consume on another.
Cross-Chain Payment Protocol Case Studies
FX Bridge for Digital Bank
Client: Series-B digital bank targeting APAC remittances.
Challenge: Legacy rails could not support a compliant cross-chain payment protocol for instant USD↔PHP swaps.
Solution: Our two-person augmented Solidity team built audited bridge contracts and integrated Chainlink price feeds, working alongside the in-house backend crew via GitLab and daily stand-ups.
Result: 64% reduction in FX settlement latency and 22% lower transaction fees within the first month.
NFT Marketplace Liquidity Router
Client: Mid-size gaming publisher launching an NFT hub.
Challenge: Needed a cross-chain payment protocol to let players buy assets on Polygon but sell on BNB.
Solution: Three Smartbrain engineers developed atomic swap contracts and an adapter SDK, delivering MVP in five sprints.
Result: Weekly active traders grew by 48%; bridge failure rate fell to 0.3%.
Carbon Credit Settlement Network
Client: Energy consortium of 12 utilities.
Challenge: Required a scalable cross-chain payment protocol for trading tokenised carbon credits across public and private chains.
Solution: A mixed senior-mid Solidity squad created a permissioned bridge with zero-knowledge attestations, integrating with ERP via REST.
Result: Settlement cycle shortened from 5 days to 6 minutes, unlocking 12 MUSD in working capital.

Our Core Services
Bridge Contract Development
Build audited token bridges that move assets and data across Ethereum, BNB, Polygon and Layer-2s. Outstaffed Solidity engineers integrate proof-of-reserve, re-org protection and slippage controls, accelerating go-live while preserving IP ownership.
Protocol Auditing & Hardening
Senior auditors review cross-chain payment protocol code for re-entrancy, nonce conflicts and oracle manipulation. Findings are patched by the same team, ensuring continuous security without separate procurement cycles.
Gas Optimisation
Specialists fine-tune Solidity bytecode and deploy Layer-2 strategies, lowering operational costs up to 40 %. Benefit from measurable savings that compound with every transaction.
SDK & dApp Integration
Developers extend your protocol with TypeScript/Go SDKs and front-end widgets, letting partners plug-in easily and boosting network adoption.
Compliance Modules
Implement address screening, FATF travel rule support and on-chain KYC directly in smart contracts, facilitating entry into regulated markets.
24/7 DevOps Support
Round-the-clock Solidity DevOps keep bridges, indexers and validators running, providing SLA-backed uptime that internal teams rarely match.
