cardano-wallet VS chainlink

It's definitely possible to pass this cost on to the buyer, I would personally start by getting the cardano-wallet stack running. If you're familiar with docker/docker-compose this is quite easy: https://github.com/input-output-hk/cardano-wallet/blob/master/docker-compose.yml

pkgname=cardano-wallet _version=2021-09-09 pkgver=20210909 pkgrel=1 pkgdesc='HTTP server & command-line for managing UTxOs and HD wallets in Cardano.' license=('Apache') arch=('any') url='https://github.com/input-output-hk/cardano-wallet' makedepends=('cabal-install-bin' 'ghc') source=("https://github.com/input-output-hk/${pkgname}/archive/v${_version}.zip") sha256sums=('868247f4a628d0d53ebfcd11bb0969ac2f22aa5579349484b1f3907497d11200')

It's not so bad. I wrote an IRC tipping bot for Cardano, was thinking it's gonna be extremely complicated, because I don't know any haskell, but it was actually pretty easy. Low level tools like cardano-cli and cardano-wallet allows you to build pretty much anything around them and all you need is to parse JSON and process HTTP requests, but it has its catches - for e-commerce I think biggest issue right now is inability to generate "unlimited" amount of receiving addresses via cardano-wallet - https://github.com/input-output-hk/cardano-wallet/issues/2921 it could be worked out by using transaction metadata, but then that's something that most wallets doesn't support right now.

I've looked at cardano-wallet but I think it's for only making transactions that are made on your server?(sorry if this isn't correct). Is there a service where they can take the address of one wallet and send to another wallet that wasn't made on your server? Or is that what the new smart contract roll outs are for? Thanks

Chainlink (LINK) – The Blockchain Oracle Giant

Chainlink allows smart contract developers to receive a wide variety of off-chain data, with the most commonly used features being receiving off-chain randomness and off-chain pricing data. Integrating your smart contracts with Chainlink provides a unique set of potential security vulnerabilities that attackers can exploit; here are the common vulnerabilities that smart contract developers & auditors need to look out for.

In some way, I'd also put Chainlink in that category since they allow to access open world data on-chain and making dapps more relevant as a result.

Smart contracts have revolutionized various industries by enabling the automation of agreements and transactions in a secure and decentralized manner. However, for smart contracts to reach their full potential, they need access to real-world data and external systems. This is where Chainlink comes into play.

I would suggest the use of an oracle like chainlink. Link: https://chain.link - I don't know exactly what your specific requirements are since I cannot review your code but a thirdparty oracle sounds like it could offer you at least some direction.

🥁 Introducing Co:OPERATE @ EthCC by Celo with Co:HOST Chainlink!

Etherisc has built a platform (Generic Insurance Framework) for decentralized insurance applications. We use blockchain technology to help make the purchase and sale of insurance more efficient, enable lower operational costs, provide greater transparency into the industry and democratize access to reinsurance. We’ve been around since 2016, have many high-profile collaborators (including Chainlink) and are proud of the innovative applications of the parametric insurance products built on our platform, including travel delay, crop and carbon credit protection.

As well as feeding real-world data to smart contracts, oracles can be used to monitor other blockchains and pass information about them between networks. Chainlink has made progress in this direction, with their Cross-Chain Interoperability Protocol (CCIP). This enables the creation of multi-chain apps. The protocol is maintained by a decentralized network of nodes. However, this is unlikely to be as secure as the chains between which messages are being sent.

Chainlink is not a blockchain - it's a "heterogeneous network", i.e. an open-source protocol for building oracle networks. Chainlink is 'blockchain-agnostic', aimed at connecting any chain to any API/external system and supporting interoperability between chains. Besides ETH, it has existing or planned integrations with: ONE, ADA, XTZ, MATIC, HBAR, DOT, BSC, ATOM, LUNA, etc.
