Which bridge should I use from Arbitrum One to Base for USDC?

Same-ecosystem USDC hops can look “too cheap”; confirm the bridge_id behind aggregator labels. Circle issues native USDC on both Arbitrum One and Base, so burn-and-mint paths compete directly with liquidity fillers here. The reference rows show what the published CCTP schedule would charge next to the live quotes.

Snapshot #45 (2026-10-24 04:05 UTC), tier by tier

  • $20: NEAR Intents 1Click 2.89 bps (ETA 27s), then Across 3.04 bps (ETA 1s), then Mayan FAST_MCTP via Mayan 3.26 bps (ETA 20 min) (21 ranked; 2 reference rows).
  • $200: Mayan FAST_MCTP via Mayan 0.33 bps (ETA 20 min), then Across 1.20 bps (ETA 1s), then NEAR Intents 1Click 1.66 bps (ETA 27s) (21 ranked; 2 reference rows).
  • $2,000: Mayan FAST_MCTP via Mayan 0.03 bps (ETA 20 min), then Across 1.02 bps (ETA 1s), then Relay 1.10 bps (ETA 2s) (21 ranked; 2 reference rows).

How wide is the USDC spread from Arbitrum One to Base?

At $200 the ranked set runs from 0.33 bps (Mayan FAST_MCTP) through a median of 27.05 bps to 141.85 bps (deBridge DLN via deBridge). 5 of 21 ranked quotes cost under 10 bps, so on a $200 transfer the gap between first and last is about $2.83.

Further down the $200 board: #4 Relay 2.05, #5 Mayan FAST_MCTP via Mayan 4.76, #6 Polymer (Standard) via LI.FI 25.00, #7 Layerswap via LI.FI 25.98, #8 LI.FI Intents via LI.FI 26.01, #9 Across via LI.FI 26.20 (bps).

Best $200 quote per API (rows returned): Mayan 0.33 bps for Mayan FAST_MCTP (2); Across 1.20 bps for Across (1); NEAR Intents 1Click 1.66 bps for NEAR Intents 1Click (1); Relay 2.05 bps for Relay (1); LI.FI 25.00 bps for Polymer (Standard) (14); Symbiosis 34.83 bps for Symbiosis (1); deBridge 141.85 bps for deBridge DLN (1).

Size sensitivity ($20 → $200 → $2,000, bps): Mayan FAST_MCTP via Mayan 3.26 → 0.33 → 0.03; Across 3.04 → 1.20 → 1.02; NEAR Intents 1Click 2.89 → 1.66 → 1.67.

Platform/integrator fees reported inside quotes on this route: LI.FI 25 bps on 14 row(s); NEAR Intents 1Click 1 bps on 1 row(s).

Quoted arrival ranges from 1s (Across) to 20 min (Mayan FAST_MCTP); these are API estimates, not measured arrivals.

Gas: every bridge on this route is shown with the same source-chain gas estimate — upswap gas basis v1, the median of the quote APIs' own estimates for Arbitrum One USDC in each run. In snapshot #45 it was $0.011: 5.5 bps of $20, 0.55 bps of $200, 0.055 bps of $2,000, or 2% of the median ranked $200 quote (27.05 bps). Arbitrum One is a rollup, so gas is paid in ETH and covers L2 execution plus the L1 data fee. The estimate is shown in its own column and never folded into bps; Across gas is never counted.

Quoted ETA by row, top 10 at $200 on Arbitrum One → Base: Mayan FAST_MCTP via Mayan 20 min, Across 1s, NEAR Intents 1Click 27s, Relay 2s, Mayan FAST_MCTP via Mayan 35s, Polymer (Standard) via LI.FI 18 min, Layerswap via LI.FI 5s, LI.FI Intents via LI.FI 6s, Across via LI.FI 1s, Circle CCTP (Fast) via LI.FI 20 min.

Practical read for USDC Arbitrum One → Base

1. The leader changes with size: $20 → NEAR Intents 1Click, $200 → Mayan FAST_MCTP, $2,000 → Mayan FAST_MCTP. Pick by the amount you actually move.

2. Across trails by only 0.88 bps at $200, so ETA (20 min vs 1s) or a frontend you trust can reasonably decide it.

3. Over 40 full runs at $200 the cheapest slot went to Mayan FAST_MCTP (36), Across (4); 4 of 14 UTC days are covered, so treat this as a short trail, not a trend.

Open items: no real-money transfer on Arbitrum One → Base yet (planned after launch); security notes for these bridges stay unverified until sourced.

How are these numbers measured?

Fixed dollar amounts, placeholder addresses, one price snapshot per run, raw responses archived with sha256. Ranked by net amount received; gas shown separately and never counted for Across.

bps
Basis points: 1 bps = 0.01% of the input amount.
Net received
amount_out_usd − fee_extra_usd. Ranking uses this.
Gas
One source-chain gas estimate per run for this source chain and token (upswap gas basis v1: median of the quote APIs’ own estimates), the same for every bridge; shown separately, not ranked. Across gas is never counted. Each API’s own figure is shown small beside it.
Quote vs arrival
Everything here is a quote. What actually arrives is only known from real-money tests (none yet).
Quotes above input
Listed at the bottom, excluded from rankings and statistics until a real transfer verifies them.
