# Why Base Chain?

> Chain selection rationale and multi-chain deployment plans

## Why Base?

Low fees and fast finality make frequent small transactions practical.

<CardGroup cols={2}>
  <Card title="Low Transaction Costs" icon="coins">
    Base's L2 architecture enables affordable fees for small P2P transactions

  <Card title="Fast Finality" icon="bolt">
    Quick confirmation times improve user experience for on/off ramp flows

## Transaction Economics

P2P on/off ramping involves frequent, often small-value transactions. Chain selection directly impacts:

* **User experience:** High gas fees make small transactions impractical
* **Protocol economics:** Transaction costs eat into merchant margins
* **Adoption:** Expensive chains limit emerging market accessibility

Base provides the cost structure needed for sustainable P2P infrastructure.

## Solana Deployment

<Info>
  Solana deployment is planned within six months of token launch.
</Info>

### Why Solana Next?

* **Even lower costs:** Sub-cent transaction fees
* **Higher throughput:** Greater transaction capacity
* **Growing ecosystem:** Expanding DeFi and payment infrastructure
* **User demand:** Strong Solana community in target markets

### Multi-Chain Vision

Chain choice does not lock the token design. The protocol can expand to multiple chains while maintaining:

* Unified governance
* Consistent token economics
* Cross-chain treasury management
* Coordinated protocol upgrades

## Technical Infrastructure

### Current Stack (Base)

* Smart contracts for escrow and matching
* On-chain parameter governance
* Treasury management
* Staking and delegation

### Planned Expansion (Solana)

* Native Solana program implementation
* Cross-chain bridge for token portability
* Unified governance across chains
* Shared liquidity pools where practical

## Deployment Timeline

| Milestone                 | Timeline               |
| ------------------------- | ---------------------- |
| Base mainnet launch       | TGE (Q1 2026)          |
| Solana testnet deployment | Q2 2026                |
| Solana mainnet launch     | Within 6 months of TGE |
| Additional chains (TBD)   | Governance-directed    |

## How Do I Separate What's Live from What's Planned?
