Custom Onchain Portfolios
Users build an auto-allocation mix across stables, yield and amplify assets, then deposits are split into that portfolio with one-to-many swaps.
Earn onchain, grow onchain.
Amasa
Spritely partnered with Amasa on product design and blockchain development for amasa.io, a non-custodial platform that helps people flow onchain earnings into a custom portfolio, lock in value from volatile tokens and grow what they earn.
We shaped the product experience around Flow, Lock in and Grow, covering wallet connection, auto-allocation portfolios, deposits and transaction clarity, while engineering smart contracts that power one-to-many swaps on Polygon so DeFi feels approachable without hiding how value moves.

What we built
A DeFi product designed around clarity, from first wallet connect through custom portfolios, deposits and onchain allocation.
Flow Earnings In
Manual and approved auto-deposits so earnings from other onchain apps can move into Amasa without a custodial handoff.
Stabilize & Grow
Risk-off paths for volatile tokens alongside growth allocations, so earners can lock in value regularly or whenever they choose.
Non-Custodial Wallet UX
Connect-wallet onboarding with self-custody front and centre. Assets stay in the user’s wallet while smart contracts execute allocation logic.
Smart Contract Allocation
Onchain contracts that batch deposits and route swaps through DEX aggregation, built for low-fee throughput on Polygon.
Dashboard & Transaction Clarity
Portfolio value, allocation detail, pending states and history designed so complex DeFi activity still reads as a clear financial product.
Built for a clear, non-custodial DeFi experience.
Frontend
React / Next.js
A fast web app experience for portfolio setup, deposits and dashboard views.
Smart Contracts
Solidity
Onchain allocation logic for deposits, one-to-many swaps and portfolio execution.
Network
Polygon
Deployed for low-fee, high-throughput allocation on Polygon Mainnet.
Backend
Node.js
API and product logic supporting app flows, indexing and wallet-connected sessions.
Design
Figma
Product strategy, prototyping and UI/UX design before development.
“Amasa is about making onchain earnings feel usable. We focused on clear product design and solid smart contract foundations so DeFi complexity stays behind the experience, not in the user’s way.”
