Round Finance

Behavior is the new guarantee.

Borrow more with less collateral.

Building the credit layer of Web3 on Solana.

[Round Finance @RoundFinanceSol]

If a user repays 24 installments on time, that information shouldn't disappear when they leave a protocol.

Credit history is valuable precisely because it's cumulative.

Reputation that can't travel isn't really reputation.

[Round Finance @RoundFinanceSol]

DeFi made assets portable. Reputation should be too.
Today, every protocol treats users like strangers, forcing overcollateralization and fragmented trust.
RoundFi turns on-chain financial behavior into portable reputation.
Trust, composable by default.

[Round Finance @RoundFinanceSol]

Most DeFi lending protocols solved capital efficiency for capital

Not for people

If access to credit requires overcollateralization, the system still mostly serves users who have liquidity

Behavioral reputation is an attempt to price reliability instead of just balance sheets

Having a Superteam is a cheat code.

Before Superteam Brasil, Brazil averaged around 10 submissions per Colosseum Hackathon. A country with 200M+ people barely showing up.

Then we launched. First hackathon: 52 submissions, winning teams, and one project accelerated by Colosseum.

Now, Frontier: 1,100+ Brazilians signed up. Brazil ranked 4th globally in registrations, 3x more than last hackathon and over 100x what we saw before Superteam existed.

But signups are easy. What matters is what gets built.

140 teams submitted projects, almost 3x as many as last hackathon. These aren't curious signups that go cold. These are builders who came to the Solana ecosystem to ship and stay.

Across the last 4 Colosseum Hackathons, Brazil went from invisible to undeniable. The quality rises every season.

Brazil is turning into a Solana powerhouse, and this is just the beginning.

Huge thanks to the entire Superteam Brasil crew, our mentors, friends, and every builder who showed up and shipped. 🇧🇷

Accelerate.

@solana_sailor @colosseum Collateral is easy to measure.
Behavior is not.
RoundFi turns recurring payment behavior into portable on-chain reputation on Solana.

What happens when financial behavior becomes infrastructure?

Share your Frontier project 👇

2,857 projects entered. Standing out won’t be easy

What makes yours special? Why should people notice it?

I’ll pick 4 and highlight them.

What is an on-chain attestation?

[Round Finance @RoundFinanceSol]

DeFi made capital permissionless. But trust is still fragmented.

Your reputation should move with your wallet — not stay trapped inside protocols.

[Round Finance @RoundFinanceSol]

Caught a regression during our internal pre-audit:
a previous release_escrow fix accidentally created an overpay path where the same checkpoint could be reused multiple times.
Fixed with cumulative-paid accounting + 6 negative regression tests.
Even fixes need adversarial review.

[Round Finance @RoundFinanceSol]

DeFi has liquidity. What it lacks is reputation.

Without behavioral trust, every wallet is treated like a stranger, so protocols demand 150% collateral.

RoundFi turns recurring on-chain behavior into portable financial reputation.

Credit shouldn’t reset at every protocol.

@0xBenii We're already there..🚀🚀

[Round Finance @RoundFinanceSol]

@solana_sailor @colosseum @toly @vibhu We are looking forward to this🚀🚀 It starts today.

[Alrimar · CTO @RoundFinanceSol @alrimar6]

@RoundFinanceSol 162 tests and still pushing harder. 🚀🧗‍♂️

[Round Finance @RoundFinanceSol]

Building on Solana changes what becomes possible.
Low fees. Fast settlement. Verifiable randomness. Real-time attestations.
Previous behavioral finance protocols lacked this stack.
Now it exists.

[Round Finance @RoundFinanceSol]

RoundFi dev update:
162 tests
18 files
active pools on Solana devnet
reputation logic evolving weekly
Still early. Still building.

[Round Finance @RoundFinanceSol]

Building behavioral credit forces you to rethink DeFi architecture entirely.
Reputation cannot depend on:
a single pool
a single yield source
a single lending market
That’s why RoundFi is modular by design.

[Round Finance @RoundFinanceSol]

Most lending protocols measure:
wallet size.
RoundFi measures:
payment behavior over time.
Very different system design implications.

[Round Finance @RoundFinanceSol]

RoundFi Development Week:
Improved reputation persistence
Redesigned pool cycle validation
Expanded stress simulations
Optimized devnet execution flow
Behavioral credit is gradually becoming infrastructure.
