On Ethereum and Base you can connect MetaMask, Coinbase Wallet, Brave, Rabby, Trust, Rainbow, OKX and other EIP-1193 / EIP-6963 wallets. On Solana you can connect Phantom or Solflare. You can also paste the address and send from any compatible wallet or exchange. Compounds are for laboratory and research use only, not for human use.

Q: Can I pay for peptides with MetaMask?

Yes. At the direct crypto pay step, choose Pay with MetaMask (or another detected EVM wallet), confirm the network and amount in the MetaMask prompt, and submit. New-U verifies the payment on-chain before fulfilment.

Q: Can I pay with Phantom or Solflare?

Yes when the invoice is on Solana. Connect Phantom or Solflare, approve the transfer in the wallet, and wait for on-chain verification. Mobile users can open the pay page inside the wallet browser when an extension is not available.

Q: Do I have to connect my wallet?

No. You can copy the receiving address and exact amount and send from any wallet or exchange withdrawal that supports the listed coin and network. Connecting is faster and reduces copy-paste mistakes.

Short version: New-U Research Compounds now supports direct wallet pay for research peptides. Connect MetaMask , Phantom , Solflare , Coinbase Wallet , Brave , Rabby , Trust , Rainbow , OKX and other injected wallets — or paste the address and send from any compatible app. Settlement is on-chain; compounds remain laboratory and research use only — not for human use. This is general information, not financial advice.

Manual copy-paste still works. The newer path is simpler: the pay page detects the wallets you already have installed, offers a Pay with … button for each one, and builds the transfer so you only approve in the wallet prompt. On mobile, deep links can open the pay page inside Phantom, Solflare or MetaMask’s in-app browser when a desktop extension is not available.

Wallets we support

Support is by network , not by a single brand. If your wallet speaks the right chain, it can pay.

Ethereum / Base (EVM): MetaMask, Coinbase Wallet, Brave Wallet, Rabby, Trust Wallet, Rainbow, OKX Wallet, Bitget and other EIP-1193 / EIP-6963 providers. When several are installed, each appears as its own button.

Solana: Phantom and Solflare — connect, sign, and send native SOL or SPL tokens when the invoice is on Solana.

Any other wallet or exchange: copy the receiving address, token contract (when shown), network and exact amount, then send manually. See the direct wallet guide.

Match coin and network. USDC on Base is not USDC on Solana. The pay page names both. Confirm them in the wallet before you approve.

How wallet pay works

Shop as usual. Add research peptides from the catalogue, sign in, and enter delivery details at checkout.

Choose direct crypto. Open the direct crypto pay step. Installed wallets are listed automatically; mobile openers appear when no extension is detected.

Connect and pay. Tap Pay with MetaMask , Pay with Phantom , or whichever wallet you use. Approve the connection, then confirm the transfer amount and network in the wallet UI.

Report sent, then wait for verify. After the wallet confirms the send, use I have sent the payment on the order page. Ops is notified; the order stays unpaid until on-chain verification matches amount, asset, network and recipient.

MetaMask, Coinbase, Brave, Rabby, Trust, Rainbow, OKX

These are EVM wallets. On desktop they usually inject a provider the page can discover (EIP-6963). You pick the brand you trust; the checkout does not force a single vendor. Coinbase Wallet, Brave, Rabby, Trust, Rainbow and OKX follow the same connect → confirm → verify loop as MetaMask.

If you use a hardware wallet behind MetaMask or Rabby, confirm the prompt on the device as well. Keep a little native gas (ETH on Ethereum/Base) so the token transfer can land in full.

Phantom and Solflare on Solana

When the invoice is Solana-native, Phantom and Solflare can sign and send without leaving the flow. Solana fees are typically tiny compared with L1 Ethereum. If you are on a phone, open the pay URL inside Phantom or Solflare’s browser so the wallet provider is available.

Why pay direct from a wallet

Fewer paste mistakes. The amount and recipient are built into the wallet prompt.

No card form. Settlement stays on-chain between your wallet and the receiving address.

Works with the wallets you already use. Multi-wallet detection means MetaMask and Rabby can coexist without fighting over window.ethereum .

Same RUO framing. Paying with crypto does not change product status — every vial is for laboratory and research use only, not for human consumption.
