Competing for: 🏆 Best Smart Contracts on Arc with Advanced Stablecoin Logic ($4,000)
Fountain is building the infrastructure layer for automated tokenization in Brazil, now integrated with Circle's Arc blockchain. We provide an API-driven stablecoin factory that enables seamless real-world asset tokenization using USDC and EURC.

In 2024, over 1 billion reais were tokenized in Brazil. But behind this growth lies chaos:
- ❌ Manual spreadsheet management
- ❌ Expensive intermediaries
- ❌ Slow, inefficient processes
- ❌ Artisanal deposit/withdrawal handling
Traditional tokenization requires multiple partners and manual intervention, making it costly and error-prone.
Fountain automates the entire stablecoin issuance lifecycle through a simple API integrated with Circle's Arc blockchain:
```javascript // Automated stablecoin minting with USDC await fountain.mint({ amount: 1000, currency: 'USDC', recipient: walletAddress, collateral: 'auto' // Supports USDC, XRP, RLUSD, tokenized securities }); ```
🔄 Instant Minting: Automated USDC/EURC issuance upon fiat deposit
🔐 Secure Escrow: Multi-collateral support with smart contract guarantees
🌐 Cross-Chain Ready: Integration with Circle's CCTP for interoperability
📊 Real-Time Transparency: Auditable balance management for hundreds of clients
⚡ High Availability: Built on Arc's robust Layer-1 infrastructure
Our advanced stablecoin logic demonstrates:
- Conditional Minting: Automated issuance based on collateral verification
- Cross-Chain Interoperability: CCTP integration for multi-chain liquidity
- Collateral Management: Dynamic collateral ratios with liquidation protection
- Batch Operations: Gas-optimized bulk minting/burning
- USDC as Gas Token: Native integration with Arc's USDC-powered operations
- CCTP Integration: Cross-chain USDC transfers for global liquidity
- Circle Gateway: Fiat on/off-ramp connectivity
- EVM Compatibility: Standard Solidity smart contracts for maximum composability
