You will need to supply the domain the order relates to and a brief describing your requirements.
PBN.LTD provides Solidity development for teams that need dependable, gas-conscious smart contracts for their Web3 products.
Our focus areas are escrow systems, DeFi protocols and agent-economy mechanisms across Ethereum, Base and other EVM-compatible chains. In this context, an agent economy means autonomous software agents transacting and cooperating on-chain, which calls for solid escrow and incentive logic to keep that cooperation trustworthy.
We treat each contract as an economic foundation, not just a piece of code, drawing on mechanism-design thinking to understand the purpose behind a system as well as its mechanics. Communication stays clear throughout, including on tighter timelines when needed.
Whether you run a small startup or an established team, this service can help move a Web3 concept into a working, security-focused product, including turnaround as quick as 3 days for simpler builds.
Your order opens its own thread here the moment it is paid, and everything about that order - questions, changes and the final report - happens in it.
We follow a clear revision policy: if the delivered contract does not match the agreed specification, we revise it until it does. Because blockchain deployments are permanent, we are unable to offer refunds once a contract has gone live on the mainnet.
Tighter deadlines can be accommodated depending on the contract's complexity. A basic escrow mechanism can typically be delivered within 3 days, while more involved agent-economy systems generally take 7-14 days. Get in touch before ordering so we can agree the exact timeline.
No. We will never ask for your private keys or seed phrases. You can deploy the contract yourself, or we can hand over the compiled code and deployment scripts so you deploy from your own secure wallet. Keeping your assets under your control is central to how we work.
Yes. We work across EVM-compatible chains, including Base, Base Sepolia and Ethereum, and we tune the code for gas efficiency on the Base network, together with full instructions for deployment.
A Solidity DeFi staking smart contract available in three packages, from source code only to full Python automation and Testnet deployment with custom token support.
A production-ready token vesting smart contract for Ethereum, BSC and Polygon, with cliff and linear release, reentrancy protection and optional Python deployment automation to lock and distribute tokens securely.
