01 Networks

The network matters more than the asset.

The same stablecoin can cost three cents or eight dollars to transfer depending on the chain, and arrive in five seconds or ten minutes. Here is what you need to choose knowingly.

Asset Network Confirmation Typical cost Note
Tether TRC-20 ≈ 1 min < $1.50 The best cost-to-speed ratio. Our default recommendation.
$ USD Coin Solana ≈ 15 s < $0.01 The cheapest on the list. Check your exchange actually offers Solana.
T Tron TRX ≈ 1 min < $0.50 Fast and cheap, but the asset itself is volatile.
B BNB / USDT BEP-20 ≈ 1 min < $0.50 A good compromise if your exchange doesn't offer TRC-20.
M Polygon POL ≈ 30 s < $0.05 Very cheap. Take care not to confuse it with Ethereum mainnet.
T Toncoin TON ≈ 10 s < $0.05 Remember the memo if your wallet asks for one.
Ł Litecoin LTC ≈ 8 min < $0.10 Robust and inexpensive, a little slower.
S Solana SOL ≈ 15 s < $0.01 The fastest. The network has rare congestion episodes.
Ξ Ethereum ERC-20 3 to 8 min $2 to $15 The most expensive. Save it for large amounts, where fees dilute.
Bitcoin BTC 10 to 60 min $1 to $8 The slowest. Two confirmations required above $1,000.
Ð Dogecoin DOGE ≈ 6 min < $0.50 Accepted, but the asset is very volatile over the confirmation window.

Timings and costs observed under normal conditions. They depend on network congestion at the time you send and can differ noticeably from these figures. The fees shown are the chain's, never ours.

02 How to choose

If

You're topping up $50 to $300

Take a stablecoin on TRC-20, BEP-20, Solana or Polygon. At these amounts, Ethereum fees would represent several percent of the operation.

If

You're topping up more than $2,000

The network matters less: a few dollars of fees become negligible. Pick whichever your exchange charges least to withdraw.

If

You're in a hurry

Solana or TON confirm in seconds. Avoid Bitcoin: on a busy network, an hour's wait is unremarkable.

If

You want to avoid volatility

Send a stablecoin. With a volatile asset the price can move between sending and confirmation — the locked rate protects you for 30 minutes, not beyond.

If

It's your first top-up

Send $50 first to validate your procedure end to end. A small test costs less than a network mistake.

If

Your wallet asks for a memo

Enter it exactly as shown on the invoice. On TON and a few other chains, a deposit without a memo may need manual intervention.

The network takes precedence over the address. An Ethereum address and a BNB Chain address look identical character for character. Sending on the wrong chain triggers no warning: the transaction succeeds, and the funds land somewhere nobody can retrieve them from. Always re-read the network before confirming.
