Basescan

Basescan is the Etherscan-family block explorer for Base. It indexes every transaction, block, contract, and account on Base, and provides a web UI for inspecting them. For LearnCoin credentials, Basescan is where the anchor transaction lives — every public verification page includes a direct link to the transaction's Basescan page.

Typical use: open a LearnCoin credential's verification page, find the "View on Basescan" link next to the anchor tx hash, click through. Basescan shows the transaction succeeded, who sent it (LearnCoin's anchoring address), what calldata was posted (the 32-byte Merkle root), and the block it landed in. The complete trust chain is auditable end-to-end with no LearnCoin infrastructure involved.

Basescan supports both mainnet (basescan.org) and Sepolia testnet (sepolia.basescan.org). Test-mode LearnCoin credentials link to sepolia.basescan.org; live-mode credentials link to basescan.org.
