We had a gnarly multi-tenant payments stack and zero appetite for another ‘rewrite in six months.’ Aristos owned the architecture, hit the dates, and our uptime story finally matched our pitch deck.

Crypto, DEX & Smart Contracts
DEX development, smart contract audits, NFT ecosystems, dApps, and custody-aware on-chain architecture with upgrade-safe patterns.
The vision
DEXes, NFT ecosystems, tokenized assets, and audited smart contracts trade reversibility for immutability. That trade only makes sense when the smallest on-chain surface is trustless and everything else stays in battle-tested off-chain infrastructure.
The challenge
Teams underestimate key custody, upgrade mechanics, and indexer failure modes. One misconfigured proxy or unchecked reentrancy vector becomes a headline—and an unrecoverable loss of user funds.
How Aristos delivers
We minimize chain surface area, formalize invariants, and prove them with fuzz and symbolic tooling where appropriate. Upgrades, timelocks, and governance hooks are documented like any other production dependency graph.
The Aristos standard
Engineering checklist we hold ourselves to—not a generic SLA slide.
- Solidity patterns reviewed against OWASP smart-contract and internal Aristos checklists
- Formalized upgrade paths: proxies, storage gaps, and migration playbooks
- Indexer redundancy and replay procedures for subgraph or custom sync workers
- Hardware wallet and multisig flows modeled with explicit signer policies
Our toolkit
Elite tools we deploy by default for this practice area.
- Foundry / Hardhat · Slither / MythX-class static analysis in CI
- OpenZeppelin contracts where applicable · The Graph or custom indexers
Engineering depth
- Gas-aware batching and mempool-aware UX (replacement fees, stuck tx recovery)
- Upgrade simulation on forked networks before mainnet promotion
- Incident runbooks for chain reorgs and RPC provider outages
