ETH Withdrawal Networks — Bitkub → Brave Wallet02.11.26

# ETH Withdrawal Networks — Bitkub → Brave Wallet

ETH ≈ **78,017 THB** / $2,309 (2026-11-02)

**Important:** the fees below are **Bitkub's fixed withdrawal fees**, not the network's real gas cost. The chain itself is usually much cheaper.

| Network | Type | Fee (ETH) | Fee (THB) | Use it when |
|---|---|---|---|---|
| **Base** | L2 (Coinbase) | 0.00005 | **3.90** | Everyday use, cheap, well supported — best default |
| **zkSync Era** | L2 (ZK) | 0.00005 | 3.90 | You use zkSync apps; slower L1 withdrawals |
| **Abstract** | L2 (new) | 0.00003988 | 3.11 | Only if you actually use Abstract |
| **Scroll** | L2 (ZK) | 0.0001 | 7.80 | You use Scroll; smaller ecosystem |
| **Ethereum** | L1 | 0.0004 | 31.21 | Large/long-term, canonical chain |
| **Optimism** | L2 | 0.0004 | 31.21 | OP ecosystem — Bitkub charges L1-level fee |
| **Arbitrum One** | L2 | 0.0004 | 31.21 | Arbitrum DeFi — same fee, no saving at withdrawal |

## Decision rule

The real choice is **where you want the ETH to live**, not the fee.

- Choose the **destination network at withdrawal**; bridging later costs gas, time, and often more than these fees.
- **Base** — sensible default: cheap, Coinbase-backed, widely supported.
- **Ethereum** — only for large amounts or canonical-chain needs; 31 THB is 50%+ of a small withdrawal.
- **Optimism / Arbitrum** — good chains, but Bitkub's 0.0004 fee matches Ethereum; no fee advantage, though on-chain gas is cheap once there.
- **Abstract** — cheapest but newest and least supported; not worth picking just to save 0.8 THB.
- **zkSync / Scroll** — fine if you use those ecosystems, otherwise unnecessary.

## Notes

- Same `0x…` address on every EVM network; the **network selection** decides where funds land.
- Check that the amount is well above the fee.
- Do not withdraw dust — the fixed fee can consume most or all of it.
- The 0.00003988 ETH currently on Abstract is the remainder of a 0.00007976 ETH withdrawal after that exact fee.
