How matches are found. Word for word: the exact same text. Edited: shares passages with this file (“99% same” means 99% of its five-word phrases also appear here; 10% or more counts). Their own version: similar meaning, or, weakest, the same name. We can’t tell which project had it first. Projects are counted among the 200 most-starred candidates, and mentions are links to the repository we found, up to 50 per site, so both counts are a floor.

The file
We split this skill into the rules it gives an agent
6 rules. About 0 are common, 4 are distinctive, and 2 are very specific to this project.
≈0
Common · estimate
Many files like this have a rule of this kind.
≈4
Distinctive · estimate
This author's own choices. Worth a look.
2
Very specific
Tied to their project's names, files or tools. Probably skip.
- Common
- Distinctive
- Very specific
- Distinctive: line 21
Use Symbiosis when the user wants to:
- Distinctive: line 35
Run the quote script:
- Distinctive: line 47
Run the swap script:
- Very specific: line 98
Use 0x0000000000000000000000000000000000000000 as address for native gas tokens (ETH, POL, BNB, AVAX, etc.).
- Very specific: line 145
Approve: If source token needs approval, script submits an ERC20 approve transaction via POST https://api.bankr.bot/agent/submit
- Distinctive: line 149
All transactions are submitted through the Bankr Submit API using the user's Bankr wallet.
≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Symbiosis
Cross-chain token swaps across 54+ blockchains. Swap any token on any chain to any token on any other chain.
When To Use
Use Symbiosis when the user wants to:
- Bridge or swap tokens between different chains (e.g., USDC from Base to Polygon, ETH from Ethereum to Arbitrum)
- Access chains beyond Bankr's native 5 (Arbitrum, Optimism, BNB Chain, Avalanche, zkSync, Linea, Scroll, Mantle, Blast, and 40+ more)
- Swap to/from Bitcoin, TON, or Tron
- Get a cross-chain quote without executing
Quick Start
Get a Quote
How much USDC will I get on Polygon if I bridge 10 USDC from Base?Run the quote script:
scripts/symbiosis-quote.py 8453 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 6 10 137 0x3c499c542cEF5E3811e1192ce70d8cC03d5c3359 6Execute a Swap
Bridge 2 USDC from Base to Polygon using SymbiosisRun the swap script:
scripts/symbiosis-swap.py 8453 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 6 2 137 0x3c499c542cEF5E3811e1192ce70d8cC03d5c3359 6Script Usage
symbiosis-swap.py
Executes a full cross-chain swap: gets quote from Symbiosis API, approves token if needed, submits swap transaction via Bankr Submit API.
scripts/symbiosis-swap.py <src_chain_id> <src_token_address> <src_decimals> <amount> <dst_chain_id> <dst_token_address> <dst_decimals> [slippage]amount— human-readable (e.g., "2" for 2 USDC, "0.1" for 0.1 ETH)slippage— optional, in basis points (default: 200 = 2%)- Reads Bankr API key from
~/.bankr/config.json - Automatically gets wallet address from Bankr
- Outputs transaction hash and Explorer tracking link
symbiosis-quote.py
Gets a quote without executing. Same arguments, no slippage parameter.

Users might say:
- "Bridge 5 USDC from Base to Arbitrum"
- "Swap 0.1 ETH from Ethereum to Polygon"
- "Move my USDC from Base to Optimism"
- "How much will I get if I bridge 100 USDC from Base to Avalanche?"
- "Cross-chain swap 50 USDC from Polygon to BNB Chain"
- "Bridge ETH from Base to Solana"
For each request: identify source chain + token, destination chain + token, look up chain IDs and token addresses from the tables above, and run the appropriate script.
How It Works
- Quote: Script calls Symbiosis API (
POST /crosschain/v1/swap) with token details and wallet address - Approve: If source token needs approval, script submits an ERC20 approve transaction via
POST https://api.bankr.bot/agent/submit - Swap: Script submits the swap transaction via
POST https://api.bankr.bot/agent/submit - Track: Returns an Explorer link for cross-chain status tracking
All transactions are submitted through the Bankr Submit API using the user's Bankr wallet. No additional wallets or keys needed.
