Wallet connection and signing
Scope account and network selection, token approvals, transaction previews and signing states. Handle rejected signatures, insufficient balances and network changes within the agreed wallet coverage.
Decentralized exchange technical services · DEX
Connect wallets, liquidity and on-chain trading for your DEX.
Develop the wallet and trading experience around an agreed network, protocol and contract version. Connect quotes, swaps, liquidity and transaction records, with clear slippage settings and recovery when signing or execution fails.
01
Choose the DEX modules to develop
Start with one supported network and trading journey. Confirm the protocol interfaces and contracts that each user action calls.
Swaps, AMMs and routing
Integrate agreed pool and router interfaces, quotes, allowance checks and swap execution. Display price impact, slippage limits, deadlines and transaction state using the chosen protocol's rules.
Liquidity views and event indexing
Scope pool data, positions and liquidity actions for supported protocol versions. Index transactions and relevant events with defined confirmation, duplicate handling and state-recovery rules.
Review a defined contract version
Identify custom contracts, privileged roles, upgrade paths and dependencies. Agree the review, findings, remediation and retest scope against an exact commit and deployment configuration.
02
Deliverables for a defined on-chain workflow
The proposal names the network, wallets, protocol versions, included contracts and integration dependencies.
User journey and contract-interface map
Document wallet actions, quote sources, token approval rules, contract calls, confirmation states and the owner of each external service.
Trading frontend and data integration
Deliver agreed wallet, swap or liquidity modules, indexing adapters, APIs and operator visibility, with source code, build instructions and environment notes.
Versioned evidence and release records
Provide agreed transaction-path tests, scoped contract findings and patch retests, plus deployment, monitoring and rollback notes. Record unresolved issues and dependency limits.
03
Verify the complete transaction path
Agree test assets, protocol versions and expected states. Separate test-network results from any production transaction evidence.
Check approvals, signing and swap states
Test wrong-network behavior, approval handling, rejected signatures, stale quotes, slippage rejection and reverted transactions. Make the resulting status and next action clear to the user.
Reconcile interface state with chain records
Check confirmed receipts, emitted events and displayed balances or positions. Exercise RPC interruptions, delayed indexing, duplicate events and the agreed confirmation policy.
Retest changes against the release scope
Tie findings and patch retests to the exact code and configuration. Review permissions, dependencies and remaining issues before the customer makes the release decision.
Make deployment and recovery reproducible
Record target addresses, environment configuration, release steps, monitoring and operating ownership. Additional networks, protocols and ongoing operations are separate scope decisions.
Common project questions
Understand the engagement before requesting a quote.
Can you build on an existing AMM or router?
Yes. The scope identifies supported contracts and protocol versions, quote and routing sources, wallet requirements and data access. Provider availability and any permitted integration terms are checked during discovery.
Can you develop custom contracts as well as the DEX frontend?
Custom contracts can be scoped after reviewing the asset model, permissions, pool or routing logic and dependencies. Implementation, contract review and patch retesting have explicit deliverables tied to a code version.
Does contract review establish that every deployment is secure?
Review covers the agreed version, contracts and assumptions, with recorded findings and retests. It does not establish the behavior of every dependency or later change. An independent audit is included only when separately agreed.
How do we start and obtain an estimate?
Share the network, protocol, desired swap or liquidity flow, current repository, contract addresses and launch target. Cost and schedule depend on those modules and dependencies; initial scope and acceptance criteria are agreed before implementation.
