Supported networks and assets
Bread is built to work across multiple blockchain networks simultaneously. Instead of forcing you to pick a single chain, Bread gives you a unified wallet that spans Spark, Solana, and Base — with your bitcoin accessible everywhere.
This article explains each network, what it’s used for inside Bread, and how they all connect behind the scenes.
Spark
Spark is a bitcoin-native layer built by Lightspark. It’s designed for instant, low-cost bitcoin transfers with true finality — meaning your transactions settle in seconds, not minutes.
When you hold bitcoin in Bread, it lives on Spark by default. This gives you the speed and cost benefits of a modern payment network while still holding real bitcoin — not a wrapped token or synthetic asset.
What Spark is used for in Bread
- Holding your primary bitcoin balance
- Sending and receiving bitcoin between Bread users
- Lightning-fast transfers with near-zero network fees
- Settling payments at Square merchants
Why Spark matters
Traditional bitcoin transactions on the base layer can take 10–60 minutes to confirm and cost several dollars in fees during busy periods. Spark eliminates both of these problems. Transactions confirm in under a second and fees are fractions of a cent — making bitcoin practical for everyday use.
Solana
Solana is a high-performance blockchain known for its speed and low transaction costs. Bread integrates with Solana to give you access to its deep DeFi ecosystem — including swaps, yield opportunities, and stablecoin infrastructure.
What Solana is used for in Bread
- Swapping between bitcoin and USDC
- Accessing DeFi yield on stablecoins
- Providing liquidity routes for the best swap rates
Solana’s role in swaps
When you swap bitcoin for USDC (or vice versa) in Bread, the trade often executes on Solana. Its sub-second block times and minimal fees mean your swap settles almost instantly, and you keep more of your money. Bread automatically routes through the best available DEX liquidity on Solana to find optimal rates.
Base
Base is an Ethereum Layer 2 network built by Coinbase. It inherits Ethereum’s security while offering significantly faster and cheaper transactions. Bread uses Base as an additional venue for swaps, payments, and asset management.
What Base is used for in Bread
- Additional swap liquidity and routing
- Access to Base-native stablecoins and DeFi protocols
- Lower-cost alternatives when Solana routes aren’t optimal
Why multiple chains?
Having access to both Solana and Base means Bread can always find you the best rate and lowest cost path for any transaction. If Solana liquidity is thin for a particular pair, Base might have a better route — and Bread checks both automatically.
How the networks connect
The key design principle behind Bread is that you should never have to think about which network you’re on. The app handles all routing, bridging, and network selection behind the scenes.
Automatic routing
When you send bitcoin, Bread picks the fastest and cheapest path. When you swap, it compares rates across all available networks and executes on the best one. When you pay at a merchant, the settlement happens on whichever network is most efficient for that transaction.
No manual bridging
In most multi-chain wallets, moving assets between networks requires manually bridging — a slow, expensive, and often confusing process. Bread eliminates this entirely. Your balance is your balance, regardless of which network it technically sits on at any given moment.
No wrapped tokens
Some wallets represent bitcoin on other chains using “wrapped” tokens — synthetic assets that are pegged to bitcoin but aren’t actually bitcoin. Bread doesn’t do this. When you hold bitcoin in Bread, it’s real bitcoin. The multi-chain infrastructure handles interoperability at the protocol level, not by creating derivative assets.
Supported assets
Bread currently supports the following assets across its integrated networks:
- Bitcoin (BTC) — Your primary asset, held natively on Spark
- USDC — USD-pegged stablecoin, available on Solana and Base
Support for additional assets will be added over time based on demand and security review. Bread prioritizes quality over quantity — every supported asset must meet strict standards for liquidity, security, and real utility.
