dApp front ends
React and Next.js interfaces with wallet connection, clear transaction states, and errors explained in plain language.
Web3 development that feels like normal software.
Velvy builds Web3 applications: the wallet connection, onchain reads and writes, the backend that indexes chain data, and the product around all of it. We work across EVM chains with ethers and viem, Solana with web3.js, Sui with Move, and TON, and we treat the user experience as seriously as the contracts. The result is a dApp that people who do not live onchain can still use.

What we build
The whole dApp, not just the contract.
Wallet and transaction flows
Signing, approvals, and transaction tracking with ethers or viem on EVM chains and web3.js on Solana.
Indexing and backends
Services that read chain events into PostgreSQL, so the app can query history quickly instead of hitting the chain on every page load.
Token and NFT features
Minting, claiming, gating, and balances surfaced in the app and connected to the contracts behind them.
TON and Telegram
TON integrations and Telegram bots for communities that already live on Telegram.
Hybrid apps
Accounts, card payments through Stripe, and conventional features alongside onchain ones, so crypto is a feature rather than a barrier.
How we build it
Chain-specific where it must be, ordinary where it can be.

01
Pick the chain for the job
Cost, speed, wallet support, and where your users already are decide the chain, not fashion.
02
Design the transaction UX
Every signature, pending state, and failure is designed, because that is where dApps lose people.
03
Index, don’t poll
Chain events flow into a database the app can query, keeping the interface fast and RPC usage sane.
04
Rehearse on testnets
Full flows run on testnets and forked networks before anything touches mainnet funds.
How to engage
Start with Milestone-based hourly.
Web3 projects usually run as milestone-based hourly work, with each milestone ending in a testnet or mainnet release you can verify yourself.
We start with paid discovery, never an unpaid test project, so the plan rests on your real requirements.

Common questions
Web3 development, answered.
Something else on your mind? Ask us directly at hello@velvy.ai, or book the intro call below.
Which blockchains do you work with?
EVM chains (Ethereum and EVM-compatible networks) with Solidity, Foundry, ethers, and viem; Solana through web3.js; Sui with Move; and TON. If you are still choosing, we compare them on cost, speed, wallet support, and where your users already are.
Do you write the smart contracts too?
Yes, in Solidity for EVM chains and in Move for Sui. Our smart contract development page covers how we write, test, and prepare contracts for an independent audit.
How do you make a dApp easier for people new to crypto?
By designing the transaction flow as carefully as any checkout: explaining each signature, showing clear pending and failed states, keeping the number of transactions low, and offering conventional accounts and card payments where they make sense.
Why does a dApp need a backend?
Reading history straight from the chain is slow and expensive. An indexer that writes chain events into PostgreSQL lets the app search, sort, and paginate quickly, and it is where offchain features like notifications live.
Can you take over an existing Web3 project?
Yes. We start with a paid review of the contracts, front end, and infrastructure, then propose what to fix, keep, or rebuild.
