Songbird

The original Flare network, now the canary network for protocol upgrades.

Explorer

Songbird is the chain Flare was launched from, and it now serves as the canary network: the experimental network where protocol-level upgrades are tested, with real consequences for real value, before they are deployed to Flare. Transactions cost SGB, and it runs the same client, consensus and contract registry as Flare. In practice its role has narrowed sharply — it is protocol rehearsal rather than production, and the token is being delisted by exchanges.

Canary network — stage 2 of the Flare upgrade path

What Songbird is for

Songbird is where Flare’s protocol upgrades are rehearsed. Flare’s development guidance sets out two tracks: application development goes from Coston2 directly to Flare Mainnet, while anything that changes the protocol must move through Songbird Testnet Coston, then Songbird Canary-Network, then Flare Testnet Coston2, and only then Flare Mainnet. Songbird is the second stage of that four-step path.

That is why Songbird still matters operationally even though day-to-day dApp work has moved elsewhere. A protocol change is proven on Songbird before it is allowed near mainnet, so a chain with modest transaction counts is serving a purpose that transaction volume alone would not suggest.

A winding-down chain, and what that means

Songbird is effectively in run-off. Its chain TVL is roughly $159,000 against Flare’s $133M — around 840 times smaller — and of the nine protocols DefiLlama tracks with a Songbird deployment, all but two hold zero value. śnosys AMM V3 (about $7.6M) and Pangolin V2 (about $2.2M) are the largest remaining deployments, and both predate Flare Mainnet; most activity has migrated.

SGB is being actively delisted. CEX.IO and CoinSpot removed SGB in February 2026, and Bithumb suspended SGB deposits and withdrawals around the July 2026 network upgrade. There is no faucet on Songbird — Flare’s own network configuration lists one as unavailable — so new developers must fund SGB themselves or build on Coston instead.

Two things still run here that do not run on Flare: Flare Confidential Compute, for which Songbird is currently the only network, and FDC-V2 attestations, which ship on Songbird before Flare. Both are worth knowing, but FCC deployed without a final audit and runs on Google Confidential Compute operated by the Flare Foundation, which is a single-vendor bootstrap rather than a settled architecture.

Shared protocols with Flare

Songbird and Flare share the client, the consensus protocol, the fee schedule and the FlareContractRegistry address, so the two are close to operationally identical. The Flare Time Series Oracle and Flare Data Connector are both available here. The difference is economic: Songbird transactions cost SGB, whose supply dynamics are separate from FLR.

Songbird’s native token wrapper is WNAT, which wraps SGB for use with DeFi protocols that expect ERC-20 semantics and to carry FTSO delegation weight (capped at 2.5% of supply).

EVM compatibility

Songbird matches Ethereum on address space and transaction encoding: 20-byte ECDSA addresses, RLP encoding, and EIP-2718 typed transactions. A contract deployed on Songbird is deployed the same way it would be on Flare, which is what makes the canary-to-mainnet path mechanical rather than bespoke.

On this marketplace

Songbird remains a supported listing chain, but treat it as run-off: liquidity is effectively one chain over, and the SGB delistings mean a buyer may struggle to exit into fiat. If you hold an item here and want to sell it, migrating to Flare Mainnet is the practical route — the Flare-native NFT marketplaces both ship one-click Songbird→Flare migration. Price items for what they are worth on this chain, not for what they would fetch on Flare.
