LINK Token Addresses — Reference
Purpose: Single reference for the correct LINK token address per chain. Use these in .env, scripts, and UIs so CCIP fee payments and approvals use the proper contract.
Chain 138 (Defi Oracle Meta Mainnet)
| Variable | Address | Notes |
|---|---|---|
LINK_TOKEN |
0xb7721dD53A8c629d9f1Ba31a5819AFe250002b03 |
Deployed on Chain 138; used for CCIP fees |
LINK_TOKEN_CHAIN138 |
Same as above | Alias for scripts that distinguish by chain |
CCIP_FEE_TOKEN |
Same as above | Fee token set on CCIPWETH9/CCIPWETH10 bridges |
Do not use Ethereum Mainnet LINK (0x514910771AF9Ca656af840dff83E8264EcF986CA) when running scripts or contracts on Chain 138 — that address has no code on 138.

Other chains (CCIP)
Use Chainlink CCIP Supported Networks for official LINK addresses. In this repo, per-chain env vars follow the pattern CCIP_<CHAIN>_LINK_TOKEN (e.g. CCIP_BSC_LINK_TOKEN, CCIP_POLYGON_LINK_TOKEN). See smom-dbis-138/.env and fund-ccip-bridges-with-link.sh.
Script defaults
- Chain 138: Scripts that run on 138 (e.g.
check-link-balance.sh,wrap-and-bridge-weth9-to-mainnet.shwhen approving LINK on 138) must default to0xb7721dD53A8c629d9f1Ba31a5819AFe250002b03whenLINK_TOKEN_CHAIN138/LINK_TOKEN_138is unset. - Mainnet: Scripts that run on Mainnet should use
0x514910771AF9Ca656af840dff83E8264EcF986CAwhen a mainnet LINK default is needed.
Quick check
To confirm the bridge fee token on Chain 138 (should match LINK above):
cast call 0x971cD9D156f193df8051E48043C476e53ECd4693 "feeToken()(address)" --rpc-url $RPC_URL_138
