​
Overview

BondKit supports bonding against ETH or an allowed ERC20 (e.g., B3). Your choice impacts UX, integrations, and liquidity at migration.

​
When to use ETH

  • Broad accessibility; most users hold ETH on Base
  • Simpler UX (no prior approvals)
  • Direct ETH liquidity at migration

​
When to use an ERC20 (e.g., B3)

  • Aligns with an existing token economy
  • Can bootstrap deeper token‑token pairs at migration
  • Requires approvals before buys/sells

​
Operational differences

  • 5% fee on buys and sells for both ETH and ERC20
  • ERC20 flows require approve before curve interactions
  • Migration pairs are created against WETH or the chosen ERC20
Confirm the allowed‑list for ERC20 quote assets with the team. By default only specific assets may be enabled.
