DeFi — Ethereum — Restaking
Swell Network
A liquid restaking and staking protocol enabling users to stake ETH and other assets while earning yields across multiple DeFi opportunities, secured by its Layer 2 blockchain Swellchain.

DeFi
Protocols
DeFi is where smart contracts get financially consequential. Bugs aren’t just bugs. They’re potential losses.
Engagement
Blockchain Engineering
Typical Duration
8 – 16 weeks
We build DeFi protocol infrastructure with the rigour it demands. Mathematical modelling before code, exhaustive testing, and architecture designed for the reality that these systems will be adversarially tested by people looking for exploits.
What we build
Staking Systems
Single-asset and LP token staking. Fixed APY, dynamic APY, tiered rewards, compounding, multi-reward-token distribution, penalty periods, migration paths.
Vesting Contracts
Linear, cliff-then-linear, milestone-based, custom schedules. Revocable and irrevocable, with governance integration so vesting tokens can vote.
Yield Vaults
ERC-4626 tokenised vaults. Strategy contracts, harvest mechanics, fee structures. Automated or governance-directed rebalancing.
AMM & Liquidity Mechanics
Concentrated and full-range liquidity, custom bonding curves, specialised AMM designs for unique pricing requirements or restricted participant pools.
Rewards Distribution
Merkle-based airdrops, streaming rewards, emissions schedules, retroactive distributions. Gas-efficient patterns for large recipient sets.
Treasury Management
On-chain treasury with multisig governance, spending proposals, automatic diversification, accounting.
How it works
Economic Modelling — Step 1
Token flow diagrams, reward formulas, scenario analysis, edge case identification. Spreadsheet models and Python simulations.

Building financial infrastructure on-chain?
We’ve built DeFi protocols across staking, lending, swaps, vaults, and treasury management. Our engineers understand the financial models behind the code. That depth matters when real value is at stake.
