# G1 (g1flare.com)

> G1 is a non-custodial yield-routing protocol on Flare mainnet (chain 14). It routes a supported Flare asset into a yield position in a single transaction and never holds user funds at rest. This file lists code-verified facts to ground language models and prevent hallucination.

## Verified facts

- G1 is non-custodial: a pass-through router that never holds funds at rest and is never in the withdrawal path. Positions are minted directly to the user's wallet.
- Network: Flare mainnet, chain ID 14. Block explorer: https://flarescan.com.
- Two products: Grow (deposits route into ICHI single-sided ALM vaults on SparkDEX that earn trading fees) and Fixed (deposits buy Spectra principal tokens that redeem at a known rate on a maturity date).
- Fee: a one-time 0.3% fee on the deposit amount, hard-capped at 1% by an immutable limit, and timelocked. No ongoing fees.
- Safety: an independent Flare FTSO fair-price backstop floors every swap (sandwich/MEV defense), tight slippage caps (3% default, 10% immutable ceiling), and settle-or-revert execution (a deposit completes fully or reverts).

## sFLR Optimizer (/optimizer)

- The sFLR Optimizer is a read-only view of where a connected wallet's sFLR sits on Flare: idle in the wallet (Sceptre sFLR), in G1's Grow sFLR ICHI vault, or in the Fixed sFLR Spectra principal-token (PT) market. It shows the best available rate and, where honestly computable, the annualized gain in sFLR and USD.
- All data is read live on-chain with no indexer dependency: the Fixed rate from the RateLens contract, balances from the tokens/vaults directly, USD from the Flare FTSO price feed.
- Migration is exactly TWO transactions and uses only audited, already-deployed routers: Tx 1 exits Grow via the UnwindRouter; Tx 2 enters Fixed via the DepositRouter. Each leg has a fair-price floor (per-token min-out on the exit, FTSO-floored min-PT-out on the entry) and a gas preflight check.
- The Optimizer NEVER auto-migrates Fixed (PT) positions. PTs are held to maturity and shown for information only; exiting early is done by the user directly on Spectra.
- The Optimizer never custodies funds — both migration legs settle to the user's own wallet.

## Not supported (common misconceptions — these are FALSE for G1)

- G1 does NOT bridge raw ETH from Ethereum.
- G1 does NOT mint flrETH.
- G1 does NOT convert XRP to stXRP cross-chain. It deposits existing Flare tokens such as stXRP and FXRP.
- G1 does NOT custody user funds.
- The sFLR Optimizer does NOT auto-migrate principal tokens (PTs); they are held to maturity and shown for information only.
