Key features

The Spectra Finance platform is built around a small set of well-defined primitives. Each one does one thing cleanly.

Principal Tokens (PT)

Buy PT at a discount. Redeem 1:1 at maturity. The spread is your fixed return — no variable rate exposure after purchase.

Yield Tokens (YT)

YT holders receive all yield generated by the underlying position over the term. Useful for yield speculation or hedging strategies.

Liquidity Pools (LP)

Provide liquidity to the PT/IBT pool. Earn trading fees and SPECTRA token incentives while maintaining partial exposure to the underlying asset.

Forge AMM

Forge is the specialised AMM powering Spectra Finance swaps. Its bonding curve accounts for time-to-maturity, producing tighter quotes than a standard constant-product pool.

MetaVaults

Auto-rolling vaults that reinvest at each maturity date. Useful for users who want fixed-rate exposure without manually managing individual terms.

Multi-network deployment

The protocol runs on Ethereum, Arbitrum, Base, Avalanche, Flare, and Katana. Each deployment shares the same contract interface and governance token.

veSPECTRA governance

Lock SPECTRA tokens to receive veSPECTRA. Vote on gauge weights, direct liquidity incentives, and propose protocol parameter changes.

Why Spectra Finance

Variable yield in DeFi can drop by 60 – 80 % in a matter of days. The Spectra Finance protocol was designed specifically to remove that uncertainty for depositors who need a reliable number to plan around.

For background on how fixed-rate instruments work in traditional finance, see the Wikipedia article on fixed income. For the Ethereum token standard underpinning PT and YT, see the ERC-20 documentation on ethereum.org.

How it works

Five steps from wallet connection to a live fixed-rate position. The whole flow takes under two minutes on any supported network.

1

Connect your wallet

MetaMask, WalletConnect, Coinbase Wallet, and most injected providers are supported. Switch to the target network inside your wallet before connecting.

2

Choose a pool

Browse active markets on the Fixed Rates page. Each row shows the underlying asset, current max APY, pool liquidity, and maturity date. Sort by any column.

3

Deposit and receive PT

Enter the amount, approve the token spend, and confirm the transaction. The Forge AMM issues PT at a discount reflecting the locked rate. You can also choose to receive YT instead.

4

Hold to maturity — or trade

Holding PT to maturity gives you the full fixed return. Selling early via the Forge pool gives you market-price exit. Either path is available without protocol permission.

5

Redeem at maturity

After the maturity timestamp, PT converts 1:1 to the underlying asset. Redemption is permissionless and settled on-chain in a single transaction.

FAQ

What is Spectra Finance?

Spectra Finance is a non-custodial DeFi protocol that splits interest-bearing tokens into Principal Tokens (PT) and Yield Tokens (YT), letting users lock in fixed rates or trade future yield independently.

How do I get a fixed rate?

Deposit a supported interest-bearing token through the app. You receive PT priced below face value. The gap between purchase price and 1.0 at maturity is your fixed return — nothing else to manage.

Is Spectra Finance safe and audited?

The protocol has passed multiple independent security reviews. Contract source code is open-source. The team behind Spectra Finance publishes audit reports publicly. That said, all DeFi carries smart-contract risk.

Can I use Spectra Finance if I am new to DeFi?

Yes. Fixed-rate positions require no ongoing management. Buy PT, wait for maturity, redeem. The interface displays plain numbers — current APY, maturity date, and expected payout — without jargon.

Why should I choose Spectra Finance over variable lending?

Variable rates on major lending markets have dropped from 8 % to under 1 % in a single week during low-demand periods. Spectra Finance sets your rate at the point of entry. What you see is what you get.

What networks does Spectra Finance support?

Ethereum mainnet, Arbitrum, Base, Avalanche, Flare, and Katana as of early 2026. New network deployments are decided through veSPECTRA governance votes.

How does the Forge integration work?

Forge is the AMM layer pricing PT and YT within the Spectra Finance platform. It uses a time-weighted curve rather than a standard x*y=k formula, which keeps spreads narrow as maturity approaches.

What happens to my tokens at maturity?

PT redeems 1:1 for the underlying asset. YT holders collect any yield that accrued during the term. Both redemptions are on-chain, permissionless, and incur only gas — no protocol fee at redemption.

Can I exit a position before maturity?

Absolutely. PT and YT are standard ERC-20 tokens. Sell them on the Spectra Finance Forge pool at any time. The exit price reflects current market rates, so early exit may yield more or less than the fixed rate.

What assets and platforms are supported?

Supported assets include stablecoins (avUSD, jEURx), liquid staking tokens (stXRP, sFLR, WFLR), and vault tokens from Yearn, Avant, YieldNest, Sceptre, and Jarvis Network — with new ones added regularly.
