Vault deposit

GET 
/v1/actions/vaults/deposit

Build calldata for an ERC-4626 vault deposit. When no wrap/swap is needed the dispatcher routes directly to vault.deposit; otherwise it falls back to the 1delta Composer (wraps native ETH, handles non-trivial composition).

This endpoint targets passive ERC-4626 vaults — share tokens that mint Diesel-style shares to a recipient. For Fluid's margin vaults (NFT-position lending markets), use /v1/actions/lending/deposit instead.

Execution mode (mode query param)

  • auto (default) — direct when payAsset === underlying and not native, otherwise composer.
  • direct — force direct; returns 400 when not eligible (e.g. native payAsset).
  • proxy — force the composer (legacy behavior).

The direct path is smaller (one call to the vault) and sidesteps the EVC indirection that the composer triggers — useful for vaults that gate on msg.sender semantics. Approval target also changes: direct → the vault; proxy → the composer.

Native deposits

Native ETH is only supported via the composer's wrap-then-deposit path (mode=proxy or auto falls back automatically). Fluid fToken vaults additionally expose a payable depositNative that skips wrapping — opt in with provider=fluid when paying with native; the dispatcher then routes to the vault directly.
